As an output, GPCTR0_GATE reflects the actual gate signal connected to
general-purpose counter 0, even if the gate is externally generated by
another PFI. This output is set to high-impedance at startup.
Figure 4-34 shows the timing requirements for GPCTR0_GATE.
Figure 4-34.
GPCTR0_GATE Signal Timing
GPCTR0_OUT Signal
This signal is available only as an output on the GPCTR0_OUT pin.
GPCTR0_OUT reflects the terminal count (TC) of general-purpose
counter 0. You have two software-configurable output options—pulse
on TC and toggle output polarity on TC. The output polarity is software
configurable for both options. This output is set to high-impedance at
startup.
Figure 4-35 shows the timing of GPCTR0_OUT.

GPCTR0_UP_DOWN Signal
This signal can be externally input on the DIO6 pin and is not available as
an output on the I/O connector. The general-purpose counter 0 counts down
