IAPEN
Description
condition is met:
(1) The accessing address is oversize.
(2) IAPCN command is invalid.
(3) IAP erases or programs updating un-enabled block.
(4) IAP erasing or programming operates under VBOD while BOIAP (CONFIG2.5)
remains un-programmed 1 with BODEN (BODCON0.7) as 1 and BORST
(BODCON0.2) as 0.
This bit should be cleared via software.
IAP enable
0 = IAP function Disabled.
1 = IAP function Enabled.
Once enabling IAP function, the HIRC will be turned on for timing control. To clear
IAPEN should always be the last instruction after IAP operation to stop internal
oscillator if reducing power consumption is concerned.
