Startup

SLEEP Mode

SLEEP Mode can be enabled in CMI 101 with I2C. The SLEEP and SLEEP_MODE bits are both set to 0 by default. No

GPIOs are configured as inputs to enable SLEEP Mode.

DPSLP Mode

DPSLP Mode can enabled in CMI 101 using GPIO5 which is configured as the PWREN input. The DPSLP and

DPSLP_MODE bits are both set to 0 by default.

DVS Mode

GPIO2 is used for DVS Mode. When GPIO2 = H, Buck2 is set to VSET0 (0.9V). When GPIO2 = L, Buck2 is set to

VSET1 (0.75V).

Voltage Select Inputs

GPIO4/7 are the voltage select inputs for Buck3/1. Note that GPIO4/7 cannot be changed while the outputs are enabled.

GPIO2 can change Buck2 on the fly.

When GPIO7 = H, Buck1 is set to its VSET0 voltage, 2.9V.

When GPIO7 = L, Buck1 is set to its VSET1 voltage, 2.5V.

When GPIO4 = H, Buck3 is set to its VSET0 voltage, 1.8V.

When GPIO4 = L, Buck3 is set to its VSET1 voltage, 1.2V.
