If set to 0, basic framing using MFT is enabled (setup via
Api429CmdTxFrmTimeIni)
. If set to a value other than 0, delay mode is
enabled allowing the user to specify the minor frame time on a frame by frame
basis. A minor frame delay can be between 5ms and 13,383 s (-200µs/+400µs)
using the following table.
Table 6.11-I

Note:
If delay mode is specified for any frame in the Replay block, then it
must be specified for all frames in the block. However, different
delay times can be specified.
Note:
If the minor frame delay specified is smaller than the amount of
time required to transmit all ARINC words defined for the frame,
all ARINC words will be transmitted in the frame, with the next
frame starting immediately following.
