Reserved bit

ON_CFG_2

R/W

Mode configuration upon falling edge applied on “ON” pin in

Mode setting 2

0: upon valid falling edge applied on “ON” pin, the device

will switch back to mode 0 setting (if the device is currently

operating in mode 0 setting, then no mode switch)

1: upon valid falling edge applied on “ON” pin, no mode

switch, the device stays in its current mode setting operation

SW2_OUT_2_OFFSET

R/W

SW2 output voltage offset selection in mode setting 2

0: SW2 Output Voltage = SW2_OUT_2_LSB[4:0] + 0 V

1: SW2 Output Voltage = SW2_OUT_2_LSB[4:0] + 1.2V

SW2_OUT_2_LSB

[4:0]

01100

R/W

SW2 default output voltage for mode setting 2 (see below)
