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

MCLR/VPP/RE3 pin, but the RB5/KBI1/PGM pin is then

dedicated to controlling Program mode entry and is not

available as a general purpose I/O pin.

While programming, using Single-Supply Program-

ming mode, VDD is applied to the MCLR/VPP/RE3 pin

as in Normal Execution mode. To enter Programming

mode, VDD is applied to the PGM 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 (VIHH applied to the MCLR/

VPP/RE3 pin). Once LVP has been disabled, only the

standard high-voltage programming is available and

must be used to program the device.

Memory that is not code-protected can be erased using

either a block erase, or erased row by row, then written

at any specified VDD. If code-protected memory is to be

erased, a block erase is required. If a block erase is to

be performed when using Low-Voltage Programming,

the device must be supplied with VDD of 4.5V to 5.5V.

Note 1: High-voltage programming is always

available, regardless of the state of the

LVP bit or the PGM pin, by applying VIHH

to the MCLR pin.

2: By default,

Single-Supply

ICSP

enabled in unprogrammed devices (as

supplied from Microchip) and erased

devices.

3: When Single-Supply Programming is

enabled, the RB5 pin can no longer be

used as a general purpose I/O pin.

4: When LVP is enabled, externally pull the

PGM pin to VSS to allow normal program

execution.
