Software reset of specific parts of the LM8328
(reserved)
Interrupt controller reset. Does not change status on IRQN ball. Only
controls IRQ module register. Interrupt status read out is not possible
when this bit is set.
0: interrupt controller not reset
1: interrupt controller reset
Timer reset for Timers 0, 1, 2
0: timer not reset
1: timer is reset
(reserved)
Keyboard interface reset
0: keyboard is not reset
1: keyboard is reset
GENIO reset
0: GENIO not reset
1: GENIO is reset.
This register allows to de-assert the POR/No Init Interrupt set every
time the device returns from RESET (either POR, HW or SW Reset),
the IRQN line is assigned active (low) and the IRQST.PORIRQ bit is
set.
(reserved)
1: Clears the PORIRQ Interrupt signalled in IRQST register.
0: is ignored
This register controls the current operating mode of the LM8328
device
(reserved)
Writing to 00 forces the device to immediately enter sleep mode,
regardless of any autosleep configuration. Reading this bit returns the
current operating mode, which should always be 01.
00: SLEEP Mode
01: Operation Mode
1x: Future modes
