DIG_Block_PG_Config
Format
status = DIG_Block_PG_Config (deviceNumber, group, config, reqSource, timebase,
reqInterval, externalGate)
Purpose
Enables or disables the pattern generation mode of buffered digital I/O. When pattern
generation is enabled, this function also determines the source of the request signals and,
if these are internal, the signal rate and gating mode.

Parameters
Input
Parameter Discussion
group is the group for which pattern generation is to be enabled or disabled.
Range:
1 or 2.
config is a flag that enables or disables pattern generation.
0:
Disable pattern generation.
1:
Enable pattern generation using request-edge latching output (input always uses
request-edge latching).
request-edge latching).
2:
Enable pattern generation without request-edge latching (input always uses
request-edge latching).
request-edge latching).
reqSource
0:
Internal. The board generates requests internally from onboard counters.
1:
External. The board accepts requests from the REQ pin on the I/O connector.
