1 Single-Supply ICSP Programming This document includes the programming specifications for the following devices: • PIC18F13K22 • PIC18F14K22 • PIC18LF13K22 • PIC18LF14K22 The LVP bit in Configuration register, CONFIG4L, enables single-supply (low-voltage) ICSP programming.
The LVP bit defaults to a ‘1’ (enabled) from the factory.
If Single-Supply Programming mode is not used, the LVP bit can be programmed to a ‘0’ and RC3/PGM becomes a digital I/O pin.
However, the LVP bit may only be programmed by entering the High-Voltage ICSP mode, where MCLR/VPP/RA3 is raised to VIHH.
Once the LVP bit is programmed to a ‘0’, only the High-Voltage ICSP mode is available and only the High-Voltage ICSP mode can be used to program the device.
Note 1: The High-Voltage ICSP mode is always available, regardless of the state of the LVP bit, by applying VIHH to the MCLR/ VPP/RA3 pin.
2: While in Low-Voltage ICSP mode, the RC3 pin can no longer be used as a general purpose I/O.

0 PROGRAMMING OVERVIEW The PIC18F1XK22/LF1XK22 devices can be programmed using either the high-voltage In-Circuit Serial Programming™ (ICSP™) method or the low-voltage ICSP method.
Both methods can be done with the device in the users’ system.
The low-voltage ICSP method is slightly different than the high-voltage method and these differences are noted where applicable.
The PIC18F1XK22 devices operate from 1.
8 to 5.
5 volts and the PIC18LF1XK22 devices operate from 1.
8 to 3.
6 volts.
All other aspects of the PIC18F1XK22 with regards to the PIC18LF1XK22 devices are identical.
2.
1 Hardware Requirements In High-Voltage ICSP mode, the PIC18F1XK22/ LF1XK22 devices require two programmable power supplies: one for VDD and one for MCLR/VPP/RA3.
Both supplies should have a minimum resolution of 0.
25V.
