timer 1 input. Input. Depending on the Timer
Mode programmed for Timer 1, this input is
used either as clock input or a control signal.
timer 0 output. Output. Depending on the
Timer Mode programmed for Timer 0, this
output can provide a single clock or a
continuous waveform.
timer 1 output. Output. Depending on the
Timer Mode programmed for Timer 1, this
output can provide a single clock or a
continuous waveform.
upper chip select. Output. Active Low. This
pin provides a chip select signal that will be
asserted (low) whenever the address of a
memory bus cycle is within the address space
programmed for that output.
