Serial Receive Frame Sync (SRFS)—This bidirectional pin is used by the
Receive section of the SSI as frame sync I/O or flag I/O. The STFS can be
used only by the receiver. It is used to synchronize data transfer and can be
an input or an output.
Port C GPIO 13 (PC13)—This pin is a GPIO pin called PC13 when the SSI
SRFS function is not being used.
After reset, the default state is GPIO input.
Timer 0 and Timer 1 Input/Output (TIO01)—This bidirectional pin
receives external pulses to be counted by either the on-chip 16-bit Timer 0
or Timer 1 when configured as input and external clocking is selected. The
pulses are internally synchronized to the DSP core internal clock. When
configured as output, it generates pulses or toggles on a Timer 0 or Timer 1
overflow event. Selection of Timer 0 or Timer 1 is programmable through an
internal register.
Port C GPIO 14 (PC14)—This pin is a GPIO pin called PC14 when the
Timer TIO01 function is not being used.
After reset, the default state is GPIO input.
Timer 2 Input/Output (TIO2)—This bidirectional pin receives external
pulses to be counted by the on-chip 16-bit Timer 2 when configured as input
and external clocking is selected. The pulses are internally synchronized to
the DSP core internal clock. When configured as output, it generates pulses
or toggles on a Timer 2 overflow event.
Port C GPIO 15 (PC15)—This pin is a GPIO pin called PC15 when the
Timer TIO2 function is not being used.
After reset, the default state is GPIO input.
