Note 1: These specifications are for the programming of the on-chip program memory EPROM through the use of the
table write instructions. The complete programming specifications can be found in: PIC18CXXX Program-
ming Specifications (Literature number TBD).
2: The MCLR/VPP pin may be kept in this range at times other than programming, but is not recommended.
