The entire data EEPROM and Flash
program memory will be erased when the
code protection is turned off. See the
“PIC12F6XX/16F6XX Memory Program-
ming Specification” (DS41204) for more
information.

GIE = 1 assumed. In this case after wake-up, the processor jumps to 0004h. If GIE = 0, execution will continue in-line.
CLKOUT is not available in XT, HS, LP or EC Oscillator modes, but shown here for timing reference.

12.14 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.
