• Manufacturer: CORERIVER Semiconductor

Address
6.17. IAP : Function Set
FFF0h
IAP call address
IAP return value
Before calling IAP function, FLASH_AEN flag in FAEN SFR must be set.
After executing IAP function, the value of PSW SFR can be changed.
During “Byte Erase” IAP functions, the part of External RAM (0600h~06FFh) is used.
Any interrupt service routine will not be executed in time since the CPU is suspended for tens of milliseconds
during executing an IAP function (Program/Erase).
