PIC18F4321 FAMILY
Even when the dedicated port is enabled, the ICSP and
ICD functions remain available through the legacy port.

23.9.2
PIC18F4221/4321 devices in 44-pin TQFP packages
also have the ability to change their configuration under
external control for debugging purposes. This allows
the device to behave as if it were a PIC18F2221/2321
28-pin device.
This 28-pin Configuration mode is controlled through a
single pin, NC/ICPORTS. Connecting this pin to V
forces the device to function as a 28-pin device; fea-
tures normally associated with the 40/44-pin devices
are disabled, along with their corresponding control
registers and bits. This includes PORTD and PORTE,
the SPP and the Enhanced PWM functionality of
CCP1. On the other hand, connecting the pin to V
forces the device to function in its default configuration.
The configuration option is only available when back-
ground debugging and the dedicated ICD/ICSP port
are both enabled (DEBUG Configuration bit is clear
and ICPRT Configuration bit is set). When disabled,
NC/ICPORTS is a No Connect pin.

23.10 Single-Supply ICSP Programming
The LVP Configuration bit enables Single-Supply ICSP
Programming (formerly known as Low-Voltage ICSP
Programming or LVP). When Single-Supply Program-
ming is enabled, the microcontroller can be programmed
without requiring high voltage being applied to the

available as a general purpose I/O pin.

If Single-Supply ICSP Programming mode will not be
used, the LVP bit can be cleared. RB5/KBI1/PGM then
becomes available as the digital I/O pin, RB5. The LVP
bit may be set or cleared only when using standard
high-voltage programming (V

standard high-voltage programming is available and
must be used to program the device.
