Bit 6-Bit 0 - LED1_PER<6:0> are used to program the time period of the open-drain output transistor at the PG
pin. The minimum period is typically 100 ms and one LSB corresponds to a 100-ms, step change in the period.

The LED2_ON and LED2_PER registers are used to control the LED2 open-drain output.
Bit 7 LED22: Control is determined by LED21 and LED22 according to the table under LED2_PER register.
Bit 6-Bit 0 - LED2_ON<6:0> are used to program the on-time of the open-drain output transistor at the LED2 pin.
The minimum on-time is typically 10 ms and one LSB corresponds to a 10-ms, step change in the on-time.

The VDCDC1 register is used to program the VMAIN switching converter.
Bit 7 - FPWM: forced PWM mode for dc-dc converters.
0 = MAIN and the CORE dc-dc converter are allowed to switch into PFM mode.
1 = MAIN and the CORE dc-dc converter operate with forced fixed-frequency PWM mode and are not
allowed to switch into PFM mode, at light load.
Bit 6-Bit 5 - UVLO<1:0>: The undervoltage threshold voltage is set by UVLO1 and UVLO0 according to the
following table, with the default value in bold.
