Bits 7 to 4: GPIO1 Configuration (GPIO1C[3:0]). This field configures the GPIO1 pin as a general-purpose input,

a general-purpose output driving low or high, or a status output. The current state of the pin can be read from

GPIOSR.GPIO1. When GPIO1 is a status output, the GPIO1SS register specifies which status bit is output.

0000 = General-purpose input

0001 = General-purpose input - inverted polarity

0010 = General-purpose output driving low

0011 = General-purpose output driving high

0100 = Status output

– non-inverted polarity

0101 = Status output - inverted polarity of the status bit it follows

0110 = Status output

– 0 drives low, 1 high impedance

0111 = Status output

– 0 high impedance, 1 drives low

1000 to 1111 = {unused values}

Bits 3 to 0: GPIO0 Configuration (GPIO0C[3:0]). This field configures the GPIO0 pin as a general-purpose input,

a general-purpose output driving low or high, or a status output. The current state of the pin can be read from

GPIOSR.GPIO0. When GPIO0 is a status output, the GPIO0SS register specifies which status bit is output.

0000 = General-purpose input

0001 = General-purpose input - inverted polarity

0010 = General-purpose output driving low

0011 = General-purpose output driving high

0100 = Status output

– non-inverted polarity

0101 = Status output - inverted polarity of the status bit it follows

0110 = Status output

– 0 drives low, 1 high impedance

0111 = Status output

– 0 high impedance, 1 drives low

1000 to 1111 = {unused values}

Note that the bits of the following registers cannot be internally connected to a GPIO configured as a status output:

GPIOSR, APLLIE.
