This reset is a MAIN domain warm reset that is executed from the SMS. This is an asynchronous reset type (takes effect immediately). This SMS reset of the Main domain is enabled only when the SMS_COLD_RESET_EN_z bit in WKUP domain CTRLMMR is '0'.
This reset behavior is same as the RESETz_REQ reset signal (RESET_REQz HW Pin) with the exception that it takes effect immediately without need for any reset isolation sequence.
When MCU domain is configured to operate independently, MCU domain reset isolation sequence is completed before propagating the RESETz to main domain.
MCU IOs are not affected.
When MCU domain is not configured as independent then, this reset will also warm reset MCU domain.
This is a MAIN domain asynchronous warm reset. Propagates immediately wihout any reset isolation sequence.
All modules in MAIN domain are reset except CTRLMMR register bits which are reset only on PORz.
IOs are not affected.
All processor cores are reset (A53SS, SMS, and R5FSS).
Reason for this reset is captured in CTRLMMR reset status register. After reset is de-asserted, device will boot-up. During device boot-up, R5FSS (secondary boot loader) will read the reset status and MCU ACTIVE MAGIC WORD registers and reconfigure the MCU domain/R5FSS processor accordingly.
