6.17. IAP (In-Application Programming)
IAP function is provided for the applications which need to save operation data/status in nonvolatile memory (on-
chip EEPROM) or to update application code (on-chip FLASH) by itself.
IAP erase byte routine (code/EEPROM) uses on-chip XRAM area(0600h~06FFh).
Program/Erase time
Program/Erase unit
IAP SFR
FAEN (F7h) : IAP Routine Access Enable Register
Code memory(62KB) can be programmed or erased during the operation of MCU.
EEPROM(2KB) can be programmed or erased during the operation of MCU.
If user software uses XRAM area(0600h~06FFh), the contents must be backup.
Program : 50us except for IAP code execution time.
Erase : 10ms except for IAP code execution time.
Program : 1 byte
Erase : 1 byte or 1 sector (256 bytes)
