Note 1: HFINTOSC Oscillator mode assumed.

2: GIE = ‘1’ assumed. In this case after wake-up, the processor jumps to 0004h. If GIE = ‘0’, execution will continue in-line.

19.8 Code Protection

If the code protection bit(s) have not been

programmed, the on-chip program memory can be

read out using ICSP™ for verification purposes.

Note:

The entire Flash program memory will be

erased when the code protection is turned

off. See the “PIC16F753/HV753 Flash

Memory Programming Specification”

(DS41686) for more information.

19.9 ID Locations

Four memory locations (2000h-2003h) are designated

as ID locations where the user can store checksum or

other code identification numbers. These locations are

not accessible during normal execution but are

readable and writable during Program/Verify mode.

Only the Least Significant 7 bits of the ID locations are

reported when using MPLAB® IDE.
