Hi Sam

 

seems there is some misunderstanding as PF8100EPES and PF8100EQES are already

programmed parts and due to "OTP (One time programmable) memory for device configuration"

as described in p.9 below datasheet, their configuration can not be changed.

PF8100_PF8200, 12-channel power management integrated circuit for high performance applications - Da...

For OTP burnning it is necessary to use MC33PF8100A0ES (Not programmed) part as

described in Table 2. Ordering information.

 

Best regards
igor
