† For this device, 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.
‡ For this device, 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).
