IRIG time source
Value Constant Description
0 API_IRIG_INTERN Switch IRIG source to internal IRIG time generator
1 API_IRIG_EXTERN Switch IRIG source permanently to external IRIG
time generator
Note: on AMC429 “free wheeling” mode is always enabled.
That means, if an external IRIG signal is detected, the
IRIG source is switched automatically to external.
Setting this parameter to API_IRIG_EXTERN leads to no
actions on the AMC429 board.
