PFI8/GPCTR0_SOURCE DGND Input
Output
PFI8/Counter 0 Source—As an input, this signal is a PFI.
As an output, this signal is the GPCTR0_SOURCE signal.
This signal reflects the actual source connected to the
general-purpose counter 0.
PFI9/GPCTR0_GATE DGND Input
Output
PFI9/Counter 0 Gate—As an input, this signal is a PFI.
As an output, this signal is the GPCTR0_GATE signal.
This signal reflects the actual gate signal connected to the
general-purpose counter 0.
GPCTR0_OUT DGND Output Counter 0 Output—This output is from the general-purpose
counter 0 output.
FREQ_OUT DGND Output Frequency Output—This output is from the frequency
generator output.
*
Indicates that the signal is active low.
