8.1.12.1.57 CM_PER_PRU_ICSS_CLKSTCTRL Register (offset = 140h) [reset = 2h]
CM_PER_PRU_ICSS_CLKSTCTRL is shown in
and described in
.
This register enables the clock domain state transition. It controls the SW supervised clock domain state
transition between ON-ACTIVE and ON-INACTIVE states. It also hold one status bit per clock input of the
domain.

Controls the clock state transition of the PRU-ICSS OCP clock
domain.
0x0 = NO_SLEEP : NO_SLEEP: Sleep transition cannot be initiated.
Wakeup transition may however occur.
0x1 = SW_SLEEP : SW_SLEEP: Start a software forced sleep
transition on the domain.
0x2 = SW_WKUP : SW_WKUP: Start a software forced wake-up
transition on the domain.
