State
SPI 0 Slave Select — SS0 is used in slave mode to indicate to the
SPI module that the current transfer is to be received.
Port E GPIO — This GPIO pin can be individually programmed as
input or output pin.
After reset, the default state is SS0.
To deactivate the internal pull-up resistor, clear bit 7 in the
GPIOE_PUR register.
Phase A1 — Quadrature Decoder, 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
6.5.8.
Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
In the 56F8346, the default state after reset is PHASEA1.
In the 56F8146, 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.
