FRM_TXICHAR0[7:0]
Transparent Mode Transmit Idle Char 0.
These bits are
used in transparent mode. They represent the first 8-bit pat-
tern the transmitter should send when there is no data
available in the FIFO. One of the four patterns can be
selected on a per-channel basis with the
FRM_HXPIDLE[1:0] (
Table 448 on page 311
) parameter.
