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 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.
Features 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.
25.10 Single-Supply ICSP Programming

Programming (formerly known as Low-Voltage ICSP
Programming or LVP). When Single-Supply Program-
