Description (Continued)
PFI9/Counter 0 Gate—As an input, this is one of the PFIs.
As an output, this is the GPCTR0_GATE signal. This signal
reflects the actual gate signal connected to the
general-purpose counter 0.
Counter 0 Output—This output is from the general-purpose
counter 0 output.
Frequency Output—This output is from the frequency
generator output.
