The AUX RAM can be powered off with or without array retention. The AUX clock is inactive during power sequencing of AUX RAM; hence, stalling all access to AUX until the RAM power sequence is complete.
AON_PMCTL:RAMCFG.AUX_SRAM_RET_EN controls RAM retention, while AON_PMCTL:RAMCFG.AUX_SRAM_PWR_OFF controls RAM power.
