State
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
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
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.
