uint32_t	pclka_hz
	Current PCLKA in Hz (for SPBR calc).
ra8_spi_mode_t	mode

bool	loopback
	SPCR2.SPLP=1: internal COPI->CIPO tie (no pins).

Detailed Description

Configuration descriptor for ra8_spi_init.

cppcheck cannot see tests/ so it flags every field as unused; each member is read in ra8_spi_init in libs/ra8_hal/src/ra8_spi_b.c.
