State
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 an 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. For details, see
Port C GPIO — This GPIO pin can be individually
programmed as an input or output pin.
In the 56F8347, the default state after reset is INDEX1.
In the 56F8147, 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. For details, see
Part
Port C GPIO — This GPIO pin can be individually
programmed as an input or output pin.
In the 56F8347, the default state after reset is HOME1.
In the 56F8147, 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.
