Detailed Description

Configuration descriptor for ra8_lpm_init.

Fields map one-to-one onto SBYCR / DPSBYCR / SSCR1 bits. The defaults match the cold-reset values:

Field	SBYCR/DPSBYCR/SSCR1 bit	Reset
opa_bus_keep	SBYCR.OPE	1
io_port_keep	DPSBYCR.IOKEEP	0
dcdc_softstart	DPSBYCR.DCSSMODE	01b
sscr_fast_return	SSCR1.SS2FR	0
sscr_low_power	SSCR1.SS2LP	00b

cppcheck does not see test sources so it sometimes flags fields as unused; every member is consumed in ra8_lpm_init in libs/ra8_hal/src/ra8_lpm.c.
