When
Section 2.1.1.1 “Single-Supply ICSP Programming”),
the Low-Voltage ICSP mode is enabled. As shown in
Figure 3-8, Low-Voltage ICSP Program/Verify mode is
entered by holding PGC and PGD low, placing a logic
high on PGM and then raising MCLR/V
this mode, the RC3/PGM pin is dedicated to the pro-
gramming function and ceases to be a general purpose
I/O pin. Figure 3-9 shows the exit sequence.
The sequence that enters the device into the Program/
Verify mode places all unused I/Os in the high-impedance
state.
