Phase A1
— Quadrature Decoder 1, PHASEA input for decoder 1.
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 56F8357, the default state after reset is PHASEA1.
In the 56F8157, 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.

Phase B1
— Quadrature Decoder ,1 PHASEB input for decoder 1.
TB1
— Timer B, Channel 1
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 56F8357, the default state after reset is PHASEB1.
In the 56F8157, 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.
