Hi community,


I'm cheking the value of MMPF0100 registers after read "Default Configuration" or "OTP" setting as attached file.

I input the values refer to Table 10 of MMPF0100 datasheet (Rev.9.0).

However, I did not understand the value of SWxxSTBY, SWxxOFF, xxxxCTL registers (highlighted registers).



Would you let me know the setting value of each SWxxSTBY and SWxxOFF register?



According to Table 88, I guess SWBSTCTL value is 0100_1000b in both case "Default Configuration" is read or "F0 OTP" is read.

Is this correct?



I believe the enable bit of VREFDDRCTL and VGENxCTL bit (bit [4]) is "1".

Is this correct?



Could you let me know the setting value of VGEN1[3:0] and VGEN3[3:0] after read "Default Configuration"? (red characters)



According to Table 10, SWDVS_CLK is "6.25 mV/us" for "Default Configuration" and "1.5625 mV/us" for "F0".

So I understand this setting is applied to all switching regulators as below, is this correct?


Default Configuration: 25mV/4.0us for SW1x, 50mV/8.0us for SW2, SW3A/B, and SW4.

F0: 25mV/16us for SW1x, 50mV/32us for SW2, SW3A/B, and SW4.
