•

GPIO_P6 (a general-purpose user-defined I/O)

•

GPIO_P31 (a general-purpose user-defined I/O)

•

PUART_TX (a peripheral UART TX output multiplexed to GPIO_P31)

•

PUART_RTS (a peripheral UART request-to-send output multiplexed to GPIO_P6)

•

SPI1_CS (a SPI interface chip-select input multiplexed to GPIO_P6)

•

A/D converter input (an A/D converter input multiplexed to GPIO_P31)

•

60Hz_mains input (a zero-crossing detector input multiplexed to GPIO_P6)

•

Quadrature decoder signal (the output of a quadrature decoder multiplexed to GPIO_P6 as an input)

•

External LPO input (LPO_IN) (an external LPO input connected to pin D6). No GPIOs are used in this case.

A system designer will select one signal function from the set of possible signal functions available at pin D6. For example, if

the system design requires a peripheral UART, the PUART_TX signal function might be assigned and configured to pin D6

(using GPIO_P31) and the other LHL GPIO, P6 in this case, is configured as input and output disabled See Section

"Peripheral UART"

For a more detailed example that assigns pins to the other PUART signal functions as well as signal function assignments for

the remaining pins in a system design, see Section
