Input,
Index1 — Quadrature Decoder 1, INDEX input
TB2 — Timer B, Channel 2
SPI 1 Master In/Slave Out — This serial data pin is an input to a
master device and output from a slave device. The MISO line of a
slave device is placed in the high-impedance state if the slave
device is not selected. The slave device places data on the MISO
line a half-cycle before the clock edge the master device uses to
latch the data. To activate the SPI function, set the INDEX_ALT
bit in the SIM_GPS register. See
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 INDEX1.
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 2 in the
GPIOC_PUR register.
Home — Quadrature Decoder 1, HOME input
TB3 — Timer B, Channel 3
SPI 1 Slave Select — In the master mode, this pin is used to
arbitrate multiple masters. In slave mode, this pin is used to
select the slave. To activate the SPI function, set the HOME_ALT
bit in the SIM_GPS register. See
Port C GPIO — This GPIO pin can be individually programmed
as input or output pin.
In the 56F8335, the default state after reset is HOME1.
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 3 in the
GPIOC_PUR register.
