Regulator SW5 is provided with 2 bits to set its mode of operation.

• The SW5_RUN_MODE[1:0] bits allow the user to change the mode of operation of the

SW5 regulators during the run state. If the regulator was programmed as part of the

power up sequence, the SW5_RUN_MODE[1:0] bits are loaded with 0b11 (autoskip)

by default. Otherwise, it is loaded with 0b00 (disabled).

• The SW5_STBY_MODE[1:0] bits allow the user to change the mode of operation of

the SW5 regulators during the standby state. If the regulator was programmed as part

of the power up sequence, the SW5_STBY_MODE[1:0] bits are loaded with 0b11

(autoskip) by default. Otherwise, it is loaded with 0b00 (disabled).

The SW5_MODE_I interrupt asserts the INTB pin when the SW5 regulator has changed

the mode of operation, provided the corresponding interrupt is not masked.

When device toggles from run to standby mode, the SW5 output voltage remains

the same, unless the regulator is enabled/disabled by the corresponding

SW5_RUN_MODE[1:0] or SW5_STBY_MODE[1:0] bits.

The SW5ILIM [1:0] bits are used to program the current limit detection level of SW5.
