PIC12F508/509
3.1.2.3 Increment Address
The PC is incremented when this command is
received. A timing diagram of this command is shown
in Figure 3-4.
It is not possible to decrement the address counter. To
reset this counter, the user must either exit and re-enter
Program/Verify mode or increment the PC from 0x3FF
for the PIC12F508 or 0x7FF for the PIC12F509 to
0x000.

3.1.2.4 Begin Programming (Externally
Timed)
A Load command must be given before every Begin
Programming command. Programming will begin after
this command is received and decoded. Programming
requires (T
PROG) time and is terminated using an End
Programming command. This command programs the
current location, no erase is performed.
