SPC5741PK1 UTEST program question

Hi expert,

I try to program SPC5741PK1 in UTest NVM block, and refer to MPC5744P Reference Manual,

I program 4 bytes each time, some address could program successful, but some have program error.

For example, when I program 0xCC 0xCC 0xCC 0xCC in address 0x400224, it has program error, and read out data is : 0xCD 0xCC 0xCC 0xCC. and when program 0x88 0x88 0x88 0x88 in address 0x400234, it have error too, and the read out value is 0x88 0x88 0x88 0x98, as the picture shows below, the left is the read out data, the right is the write date file.

I found in the RM that some address in Utest area are mapping to register, does that means it will have error when programing, would you please give me some advice for this, Thanks!

 

Shirley
