Two methods are available to enter Program/Verify

selection and must be used if the INTOSC and internal
MCLR options are selected (FOSC<2:0> = 100 or 101
and MCLRE = 0). The V

The second entry method, “V

programming the device when V

Program/Verify mode. See the timing diagram in
Figure 3-2.
Once in this mode, the program memory, data memory,
and configuration memory can be accessed and
programmed in serial fashion. ICSPDAT and ICSPCLK
are Schmitt Trigger inputs in this mode. RB6 is tri-state,
regardless of fuse setting.
The sequence that enters the device into the
Programming/Verify mode places all other logic into the
Reset state (the MCLR pin was initially at V
Therefore, all I/Os are in the Reset state (high-
impedance inputs) and the Program Counter (PC) is
cleared.
To prevent a device configured with INTOSC and
internal MCLR from executing after exiting Program/
Verify mode; V
