2.4.5.1 PICKIT SERIAL INTERFACE
Table 2-2 shows the pin number assignment for the different signals for each of the
supported interface protocols (SPI, I
2
C, etc.)
2.4.5.2 ICSP INTERFACE
The ICSP interface allows a PICmicro MCU device to be programmed with
programmers that support this interface, such as the PICkit 2 programmer (part number
PG164120). Table 2-3 shows the pin number assignment for the ICSP signals.
