Generally, no code modification is required when migrating from MMPF0100 to

MMPF0100A part. The differences between these two parts are summarized in the Table 2

of the MMPF0100 Data Sheet Rev.12 document, available on the MMPF0100

Documentation web page:

Have a great day,

I found old pmu sw4 default output is 3.15v，use the same code, new pmu sw4 output 1.8v

Can you tell me how to modify sw4 from 1.8v to 3.15v ?
