The IPUx subsystem is divided into two power domains (PD_IPU and PD_COREAON), which are controlled by the PRCM module.
The PD_IPU power domain is the main power domain and includes all the IPUx subsystem components (two Arm Cortex-M4 processors, IPUx_UNICACHE, IPUx_ROM and IPUx_RAM memories, and emulation\debug modules) except the IPUx_WUGEN.
The PD_COREAON power domain is an always-on power domain. The PD_COREAON power domain contains the IPUx_WUGEN, which generates a wake-up request from external interrupts. By this separate PD_COREAON power domain, the wake-up request can be generated even when the PD_IPU power domain is in OFF or RET state.
