WARM_RESET(2)N12IOOpen DrainOpen-drain fail-safe warm reset signal. Can be driven from PMIC for diagnostic or can be used as status signal that the device is going through reset.
SOP2P13IThe SOP pins are driven externally (weak drive) and the AWR device senses the state of these pins during bootup to decide the bootup mode. After boot the same pins have other functionality.
[SOP2 SOP1 SOP0] = [0 0 1] → Functional SPI mode
[SOP2 SOP1 SOP0] = [1 0 1] → Flashing mode
[SOP2 SOP1 SOP0] = [0 1 1] → debug mode
