2.5
The High-Voltage ICSP Program/Verify mode is
entered by holding PGC and PGD low, and then raising
MCLR/V
the code memory, data EEPROM, ID locations and
Configuration bits can be accessed and written in serial
fashion.
The sequence that enters the device into the
Programming/Verify mode places all unused I/Os in
the high-impedance state.
FIGURE 2-10:
2.6
When the LVP Configuration bit is ‘1’ (see Section 5.3
“Single-Supply ICSP Programming”), the Low-
Voltage ICSP mode is enabled. 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
dedicated to the programming function and ceases to
be a general purpose I/O pin.
The sequence that enters the device into the
Programming/Verify mode places all unused I/Os in the
high-impedance state.

The PGC pin is used as a clock input pin and the PGD
pin is used for entering command bits and data input/
output during serial operation. Commands and data are
transmitted on the rising edge of PGC, latched on the
falling edge of PGC and are sent Least Significant bit
(LSb) first.
2.7.1
All instructions are 20 bits, consisting of a leading 4-bit
command, followed by a 16-bit operand which depends
on the type of command being executed. To input a
command, PGC is cycled four times. The commands
needed for programming and verification are shown in
Table 2-3.
TABLE 2-3:
Depending on the 4-bit command, the 16-bit operand
represents 16 bits or 8 bits of data.
Throughout this specification, commands and data are
presented as illustrated in Table 2-4. The 4-bit com-
mand is shown MSb first. The command operand or
“Data Payload” is shown <MSB:LSB>. Figure 2-12
demonstrates how to serially present a 20-bit
command/operand to the device.
