The Byte erase program procedure in user program mode
1. Page buffer clear (FMCR=0x01)
2. Write ‘0’ to page buffer
3. Set flash sector address register (FSADRH/FSADRM/FSADRL).
4. Set flash identification register (FIDR).
5. Check the UserID for to prevent the invalid work
(Note)
.
6. Set flash mode control register (FMCR).
7. Erase verify
Notes) 1. Please refer to the chapter “Protection for Invalid Erase/Write”.
2. On flash memory erase and write, it should be disabled the RXE0/1 bit of USI0CR2/USI1CR2
register.
