#include <ra8_i2c.h>

Data Fields
uint8_t	own_addr_7b
	7-bit own address to answer on.
ra8_i2c_peripheral_slot_t	slot
	Own-address comparator slot.
bool	general_call
	Also answer the general-call addr.
bool	clock_stretch
	Arm ICMR3.WAIT clock stretching.
bool	irq_enable
	Arm ICIER RIE / TIE / SPIE.

Detailed Description

Configuration descriptor for ra8_i2c_peripheral_init.

Selects the 7-bit own address, the comparator slot that holds it, whether to also answer the I2C general-call address, whether to arm ICMR3.WAIT-based clock stretching so the servicing loop has time to handle each byte, and whether to arm the ICIER target interrupts. cppcheck cannot see tests/ so it flags the members as unused; all five are read in ra8_i2c_peripheral_init.

Invariant

own_addr_7b is a 7-bit value (<= 0x7F) and slot is one of the three k_ra8_i2c_peripheral_slot_* values.
