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.
