Detailed Description

One GPTP timer unit's register block (HUM Ch 35.3.2 / 35.3.3).

The block repeats every k_ra8_gptp_timer_stride bytes starting at k_ra8_gptp_off_timer0, matching the + 0x40 x t addressing of HUM Table 35.3 p 1926. Reserved gaps are spelled out so the members always line up with the manual.

The unit holds three views of the same counter: the 78-bit GPTP time ({PTPGPTPTMtU, PTPGPTPTMtM, PTPGPTPTMtL}, seconds in bits [77:30] and nanoseconds in [29:0]), and the 64-/32-bit AVTP nanosecond views derived from it (HUM 35.5.1 p 1951). PTPTIVCt sets the per-clk increment and {PTPTOVCtU, PTPTOVCtM, PTPTOVCtL} the additive offset.

Invariant

Reading PTPGPTPTMtL latches PTPGPTPTMtM / PTPGPTPTMtU, so an ordered read of L, M, U is atomic (HUM 35.4.1.3.4 p 1946).

Writing PTPTOVCtL commits the whole 78-bit offset, so U and M must be written first (HUM 35.4.1.3.1 p 1944-1945).

Example:

volatile r_gptp_timer_regs_t* t = &ra8_gptp()->TIMER[k_ra8_gptp_timer_0];
const uint32_t ns = t->PTPGPTPTML;
