Description (Continued)
PFI2/Convert—As an input, this is one of the PFIs.
As an output, this is the CONVERT* signal. A high-to-low
edge on CONVERT* indicates that an A/D conversion is
occurring.
PFI3/Counter 1 Source—As an input, this is one of the
PFIs.
As an output, this is the GPCTR1_SOURCE signal. This
signal reflects the actual source connected to the
general-purpose counter 1.
PFI4/Counter 1 Gate—As an input, this is one of the PFIs.
As an output, this is the GPCTR1_GATE signal. This signal
reflects the actual gate signal connected to the
general-purpose counter 1.
Counter 1 Output—This output is from the general-purpose
counter 1 output.
PFI5/Update—As an input, this is one of the PFIs.
As an output, this is the UPDATE* signal. A high-to-low
edge on UPDATE* indicates that the analog output primary
group is being updated.
PFI6/Waveform Trigger—As an input, this is one of the
PFIs.
As an output, this is the WFTRIG signal. In timed analog
output sequences, a low-to-high transition indicates the
initiation of the waveform generation.
PFI7/Start of Scan—As an input, this is one of the PFIs.
As an output, this is the STARTSCAN signal. This pin
pulses once at the start of each analog input scan in the
interval scan. A low-to-high transition indicates the start of
the scan.
PFI8/Counter 0 Source—As an input, this is one of the
PFIs.
As an output, this is the GPCTR0_SOURCE signal. This
signal reflects the actual source connected to the
general-purpose counter 0.
