Detailed Description

USB IRQ dispatch / event callbacks / power + host-mode bring-up.

Tag: [Ring 3 / HAL] {World: NS}

Two cohesive groups split out of ra8_usb.c to keep every translation unit under the 1000-line cap:

The interrupt-delivery + power surface: the per-controller event callback table, ra8_usb_dispatch (W0C-correct INTSTS0 ack + handler fan-out), ra8_usb_intsts0_snapshot, and the module-stop enter / exit helpers.
The host-mode lifecycle bring-up (ra8_usb_host_init / ra8_usb_host_deinit / ra8_usb_host_bus_reset / ra8_usb_host_set_uact / ra8_usb_host_setup_request), peer of the device-mode lifecycle in ra8_usb_device.c.

The shared register helpers and the USBHS PHY bring-up it calls are declared in ra8_usb_internal.h. Modelled on FSP r_usb_hreg_access.c; no FSP source ships in this tree.

Function Documentation

◆ internal_cb_slot()

uint8_t internal_cb_slot ( ra8_usb_speed_t speed )

static

Map a USB speed enum to the per-controller callback slot index.

Two slots exist: k_ra8_usb_cb_slot_fs for the USBFS controller and k_ra8_usb_cb_slot_hs for the USBHS controller. Every code path that indexes s_usb_fn[] or s_usb_ctx[] goes through this helper so we never confuse the two.

Parameters

[in] speed Controller selector (FS or HS).

Returns: Slot index in s_usb_fn[] / s_usb_ctx[].

Return values

k_ra8_usb_cb_slot_hs	speed == k_ra8_usb_speed_hs.
k_ra8_usb_cb_slot_fs	Any other speed value (FS default).

Precondition: speed is a valid ra8_usb_speed_t enum.; s_usb_fn / s_usb_ctx storage is in scope.

Postcondition: No global state is touched; the helper is pure.; Result is always < k_ra8_usb_cb_slot_n.

Note: Pure / thread-safe.

Since: 0.1.0

◆ internal_host_hs_bringup()

ra8_err_t internal_host_hs_bringup ( volatile r_usb_regs_t * reg )

static

Bring the USBHS instance up in HOST role (PHY + SYSCFG bits).

The HS PHY needs the full UTMI bring-up (CLKSEL, DIRPD and PLLRESET release, SUSPENDM, PLLLOCK) before the module can operate; reuse the device-mode sequence, which ends with USBE=1 and the device-polarity DRPD=0. Then flip the role bits: HUM Ch 37.2.1 requires DCFM to be changed while USBE=0, so drop USBE, set DCFM (host controller) + DRPD (host pull-downs) + CNEN, and re-enable. CNEN (single-ended receiver enable) is required for the HS PHY to report line state / attach at all – without it LNST reads SE0 forever and no ATTCH ever latches (HUM Ch 37.2.1 p 2062).

Parameters

[in] reg HS register block (must be the USBHS instance).

Returns: Passthrough from the PHY bring-up.

Return values

k_ra8_ok	PHY locked; SYSCFG carries the host role.
k_ra8_err_hw_timeout	The UTMI PLL never locked.

Precondition: MSTPB12 is ungated and USB60CLK (PLL2P/4) is running.; Single-threaded init context.

Postcondition: SYSCFG = HSE | DCFM | DRPD | CNEN | USBE with the PHY powered.; The caller still programs DVSTCTR0 / FIFO / DCP defaults.

Note: Not thread-safe; init context only.

◆ internal_host_init_defaults()

void internal_host_init_defaults ( volatile r_usb_regs_t * reg )

static

Program the host-mode FIFO / DCP / interrupt-enable defaults.

Shared tail of host bring-up for both controller instances: 16-bit FIFO port widths (the per-access width is re-selected by priv_select_cfifo), DCP defaults with a 64-byte max packet, USBADDR=0 (newly attached devices answer at the default address), and the host interrupt-enable mask (per-pipe ENB registers stay clear; the transfer engines arm exactly what they wait on).

Parameters

[in] reg Selected controller register block.

Precondition: SYSCFG already carries the host role (DCFM | DRPD | USBE).; Single-threaded init context.

Postcondition: FIFO selects, DCP, USBADDR and INTENB0/1 hold the defaults.; BRDYENB / NRDYENB / BEMPENB are cleared.

Note: Not thread-safe; init context only.

◆ internal_host_syscfg_word()

uint16_t internal_host_syscfg_word ( ra8_usb_speed_t speed )

static

Build the host-mode SYSCFG word.

Sets SCKE | DCFM | DRPD | USBE; adds HSE for the HS instance. DPRPU is intentionally not set (device-mode pull-up).

Parameters

[in] speed See implementation.

Returns: Result code.

Return values

k_ra8_ok Operation succeeded.

Precondition: Module state is consistent.; Module state is consistent.

Postcondition: Caller-visible state matches the documented contract.; Caller-visible state matches the documented contract.

◆ ra8_usb_attach_handler()

void ra8_usb_attach_handler	(	ra8_usb_speed_t	speed,
		ra8_usb_event_fn_t	fn,
		void *	ctx )

Install (or detach) the per-controller USB event handler.

Each controller (USBFS, USBHS) has its own callback slot, so one firmware image can run different upper-layer drivers on each controller simultaneously (e.g. USBX/DCD bridge on USBHS, a bare-CDC handler on USBFS). The matching ra8_usb_dispatch(speed) only fires the callback registered for that speed.

Parameters

[in]	speed	Which controller's callback slot to update.
[in]	fn	Callback. NULL detaches.
[in]	ctx	Context passed to fn.

Slot replacement performs no fallible work; callers observe completion when this function returns.

Precondition: speed is k_ra8_usb_speed_fs or k_ra8_usb_speed_hs.; Caller serializes this update with ra8_usb_dispatch(speed).

Postcondition: Subsequent ra8_usb_dispatch(speed) calls route through fn.; Passing NULL for fn prevents subsequent callback invocation for the selected controller.

Note: Not thread-safe.
