Phase A1 — Quadrature Decoder 1, PHASEA input for decoder

TB0 — Timer B, Channel 0

SPI 1 Serial Clock — In the master mode, this pin serves as an

output, clocking slaved listeners. In slave mode, this pin serves

as the data clock input. To activate the SPI function, set the

PHSA_ALT bit in the SIM_GPS register. For details, see Part

6.5.8.

Port C GPIO — This GPIO pin can be individually programmed

as an input or output pin.

In the 56F8335, the default state after reset is PHASEA1.

In the 56F8135, the default state is not one of the functions

offered and must be reconfigured.

To deactivate the internal pull-up resistor, clear bit 0 in the

GPIOC_PUR register.

SPI 1 Master Out/Slave In — This serial data pin is an output

from a master device and an input to a slave device. The master

device places data on the MOSI line a half-cycle before the clock

edge the slave device uses to latch the data. To activate the SPI

function, set the PHSB_ALT bit in the SIM_GPS register. For

details, see Part 6.5.8.

Port C GPIO — This GPIO pin can be individually programmed

as an input or output pin.

In the 56F8335, the default state after reset is PHASEB1.

In the 56F8135, the default state is not one of the functions

offered and must be reconfigured.

To deactivate the internal pull-up resistor, clear bit 1 in the

GPIOC_PUR register.
