1.2 Pin Utilization
Five pins are needed for ICSP™ programming. The
pins are listed in Ta bl e 1- 1 and Table 1-2 .
TABLE 1-1: PIN DESCRIPTIONS DURING PROGRAMMING – PIC16(L)F1826, PIC16(L)F1827
Pin Name
During Programming
Function Pin Type Pin Description
RB6 ICSPCLK I Clock Input – Schmitt Trigger Input
RB7 ICSPDAT I/O Data Input/Output – Schmitt Trigger Input
RA5/MCLR
/VPP Program/Verify mode P
(1)
Program Mode Select/Programming Power Supply
V
DD VDD P Power Supply
V
SS VSS P Ground
Legend: I = Input, O = Output, P = Power
Note 1: In the PIC12(L)F1822 and
PIC16(L)F182X, the programming high voltage is internally generated. To activate the
Program/Verify mode, high voltage needs to be applied to MCLR
input. Since the MCLR is used for a level source,
MCLR
does not draw any significant current.
