Hi,

I am working with non-programmed part PF1550. I have read its datasheet and the OTP programming Instructions AN12408. But when trying to follow the programming example, I encounter some weird register addresses like 0xC0, 0xC1, 0xC2,..., for which I cannot find descriptions. Which documents should I read to find these registers?

Example instructions from AN12408:

...
//===========================================================================
// Commands are for OTP programming setting
//===========================================================================
WRITE_OTP_CONTROLLER:PMIC:0xC0:0xA5
WRITE_OTP_CONTROLLER:PMIC:0xC1:0x1C
WRITE_OTP_CONTROLLER:PMIC:0xC2:0x38
WRITE_OTP_CONTROLLER:PMIC:0xC8:0x0F
WRITE_OTP_CONTROLLER:PMIC:0xC9:0x02
WRITE_OTP_CONTROLLER:PMIC:0xCA:0x07
WRITE_OTP_CONTROLLER:PMIC:0xCD:0x35
EXEC_DELAY:1000
WRITE_OTP_CONTROLLER:PMIC:0xC0:0x96
EXEC_DELAY:200
READ_OTP_CONTROLLER:PMIC:0xC6
