PFI3/GPCTR1_
SOURCE
DGND
Input
PFI3/Counter 1 Source—As an input,
this is one of the PFIs.
Output
As an output, this is the
GPCTR1_SOURCE signal. This
signal reflects the actual source
connected to general-purpose
counter 1.
PFI4/GPCTR1_GATE
DGND
Input
PFI4/Counter 1 Gate—As an input,
this is one of the PFIs.
Output
As an output, this is the
GPCTR1_GATE signal. This signal
reflects the actual gate signal
connected to the general-purpose
counter 1.
GPCTR1_OUT
DGND
Output
Counter 1 Output—This is the
general-purpose counter 1 output.
PFI5/UPDATE
DGND
Input
PFI5/Update—As an input, this is one
of the PFIs.
Output
As an output, this is the UPDATE*
signal. A high-to-low edge on
UPDATE* indicates that the analog
output primary group is updating.
PFI6/WFTRIG
DGND
Input
PFI6/Waveform Trigger—As an input,
this is one of the PFIs.
Output
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/STARTSCAN
DGND
Input
PFI7/Start of Scan—As an input, this
is one of the PFIs.
Output
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.
