† The CLKOUT2 pin is multiplexed with the GP[2] pin. Default function is CLKOUT2. To use this pin as GPIO, the GP2EN bit in

the GPEN register and the GP2DIR bit in the GPDIR register must be properly configured.

‡ The external interrupts (EXT_INT[7−4]) go through the general-purpose input/output (GPIO) module. When used as interrupt

inputs, the GP[7−4] pins must be configured as inputs (via the GPDIR register) and enabled (via the GPEN register) in addition
to enabling the interrupts in the interrupt enable register (IER).

§ This pin functions as the Big Endian mode correctness and is used when Big Endian mode is selected (LENDIAN = 0)
