PIC16F627A/628A/648A
The optional 16-bit data word will either be an input to,
or an output from the PIC
on the command. Load Data commands will be input,
and Read Data commands will be output. The 16-bit
data word only contains 14 bits of data to conform to the
14-bit program memory word. The 14 bits are centered
within the 16-bit word, padded with a leading and trail-
ing zero.
Program/Verify mode may be entered via one of two
methods. High voltage Program/Verify is entered by
holding CLOCK and DATA pins low while raising MCLR
first, then V
Program/Verify mode is entered by raising V
MCLR and PGM, as shown in Figure 2-3. The PC will
be set to ‘0’ upon entering into Program/Verify mode.
The PC can be changed by the execution of either an
increment PC command, or a Load Configuration
command, which sets the PC to 0x2000.
All other logic is held in the Reset state while in
Program/Verify mode. This means that all I/O are in the
Reset state (high-impedance inputs).
If LVP is not being used for programming and the LVP
Configuration bit is set (i.e., LVP feature is enabled),
the PGM pin must not be allowed to toggle while
programming. The PGM pin is edge sensitive and if an
edge is detected during programming, it may cause the
PC to reset. If the LVP feature is disabled, the PGM pin
will have no effect on programming.

If the LVP fuse is enabled, PGM should be
