S32K314 programming error

Hello

When I tried to write data to the DFLASH using debug mode, it failed.

Below is a rough outline of my code.

write 0xFFFFF800 to 0x40268350

wtire 0x10000000 to PFCPGM_PEARR_L register

write 0xFFFFFFFF to Program DATA0

set MCR[ERS] to 1 MCR[ERS] choose sector

Set MCR[EHV] to 1

wait MCRS[DONE] be 1 check MCRS[PEG]

set MCR[EHV] to 0 SETMCR[ERS]to 0

after erase 11 sectors

wtire 0x10000000 to PFCPGM_PEARR_L register

write 256 bit data to DATA0~DATA7

set MCR[PGM] to 1 set MCR[EHV] to 1

read MCRS register get 0x0000C100

But when I looped for the second time

wtire 0x10000000 to PFCPGM_PEARR_L register

write 256 bit data to DATA0~DATA7

set MCR[PGM] to 1 set MCR[EHV] to 1

read MCRS register get 0x00008100

I'd like to know what might be causing this situation.

set 0 to MCR[EHV] set 0 to MCR[PGM/ERS]
