6 / 456 page  MEC1322 DS00001719D-page 6 2014 - 2015 Microchip Technology Inc. TABLE 1-1: MEC1322 128 VTQFP PIN CONFIGURATION Note 1: The XTAL2 pin can be used as a single ended clock input. See Note 9 in Section 1.6, "Notes for Tables in this Chapter," on page 39. 2: See Note 10 in Section 1.6, "Notes for Tables in this Chapter," on page 39 for information about the SPI pins. 3: The VCC1_RST#/GPIO131 pin cannot be used as a GPIO pin. The input path to the VCC1_RST# logic is always active and will cause a reset if this pin is set low in GPIO mode. 4: The GPIO041 pin defaults to output low. This pin must be reprogrammed to the GPIO function upon power- up. 128 VTQFP Number Pin Name Pin Ref.
