Startup

SLEEP Mode

CMI 110 does not use SLEEP Mode.

DVS Mode

CMI 110 can DVS Buck4. EXT_PG is the DVS control input. When EXT_PG = L, Buck4 = 1.8V. When EXT_PG = H,

Buck4 = 1.2V

POK Thresholds

POK_UV = 2.8V

POK_OV = 3.6V

The PG pin is not functional with CMI 110. Leave the PG pin floating.

POK

The POK pin is not functional with CMI 110. Leave the POK pin floating.

EXT_EN

The EXT_EN pin is not functional with CMI 110. Leave the EXT_EN pin floating.

nRESET

nRESET is triggered from LDO1. It goes high 1ms after LDO1 goes into regulation. After power up, set register 0x00h

to a value of 0x20h to prevent nRESET from asserting low during normal operation. This is required because different

outputs are turned on and off in normal operation.
