Code Protection
If

code
protection
bit(s)
have
not
been
programmed, the on-chip program memory can be
read out using ICSP for verification purposes.
12.9
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
used.

Note
1:
XT, HS or LP Oscillator mode assumed.
2:
TOST = 1024 TOSC (drawing not to scale). This delay does not apply to EC, INTOSC and RC Oscillator modes.
3:
GIE = ‘1’ assumed. In this case after wake-up, the processor jumps to 0004h. If GIE = ‘0’, execution will continue in-line.
4:
CLKOUT is not available in XT, HS, LP or EC Oscillator modes, but shown here for timing reference.
Note:
The entire Flash program memory will be
erased when the code protection is turned
off.
