As an output, GPCTR0_GATE reflects the actual gate signal connected to
general-purpose counter 0, even if the gate is being externally generated by
another PFI. This output is set to high-impedance at startup.
general-purpose counter 0, even if the gate is being externally generated by
another PFI. This output is set to high-impedance at startup.
Figure 4-28 shows the timing requirements for the GPCTR0_GATE signal.

GPCTR0_OUT Signal
This signal is available only as an output on the GPCTR0_OUT pin.
The GPCTR0_OUT signal reflects the terminal count (TC) of
general-purpose counter 0. You have two software-selectable output
options—pulse on TC and toggle output polarity on TC. The output
polarity is software-selectable for both options. This output is set to
high-impedance at startup. Figure 4-29 shows the timing of
GPCTR0_OUT.
