ISPTM (ON-BOARD PROGRAMMING) SECTOR

ISPTM sectors located in program memory area can store on board program software (boot program code for

upgrading application code by interfacing with I/O pin). The ISPTM sectors can not be erased or programmed by

LDC instruction for the safety of On Board Program software.

The ISP sectors are available only when the ISP enable/disable bit is set 0, that is, enable ISP at the Smart

Option. If you don't like to use ISP sector, this area can be used as a normal program memory (can be erased or

programmed by LDC instruction) by setting ISP disable bit ("1") at the Smart Option. Even if ISP sector is

selected, ISP sector can be erased or programmed in the Tool Program mode, by Serial programming tools. The

size of ISP sector can be varied by settings of Smart Option. You can choose appropriate ISP sector size

according to the size of On Board Program software.
