TABLE 1-1: PIN DESCRIPTIONS (DURING PROGRAMMING): PIC16F87XA
Pin Name
During Programming
Function Pin Type Pin Description
RB3 PGM I Low voltage ICSP™ programming input if LVP
configuration bit equals ‘1’
RB6 CLOCK I Clock input
RB7 DATA I/O Data input/output
MCLR
VTEST MODE P* Program Mode Select
V
DD VDD P Power Supply
VSS VSS P Ground
Legend:I = Input, O = Output, P = Power
* To activate the Programming mode, high voltage needs to be applied to the MCLR
input. Since MCLR is used for a
level source, this means that MCLR
does not draw any significant current.
