FRM_BOME
Transmit Bit-Oriented Message Enable. A 1 indicates that the
BOM message register has been initialized and should be transmit-
ted on the data link of the ESF frame. The pattern will continue to
be transmitted until the enable is removed. When set to 0, the BOM
transmission will stop immediately without completing the current
pattern transmission or without completing the series of 10 pat-
terns.
5:0 FRM_TBOM[5:0] Transmit Bit-Oriented Message. Indicates the contents of the
BOM to be transmitted when enabled with FRM_BOME. A pattern
of 111110 implies a BOM of 0111110011111111 with the
0
right-most bit being transmitted first.

FRM_BOMC_IS BOM Complete Interrupt. (Clear on write.) A 1 indicates that
the BOM register contents have been transmitted 10 times over
the data link of the ESF frame.

FRM_TXSE_IS Tx Stack Empty Interrupt. (Clear on write.) A 1 indicates that
the Tx stack is empty. 0 indicates that the host has finished
updating the stack. The Tx data link block sets this bit when the
stack is empty, and needs to be filled if the D bits or Sa bits
require changing. If the stack is not refilled, the old data will be
retransmitted.The new data can be written anytime without
interfering with the current transmission. The stack needs to be
updated within 9 ms for an SLC-96 link or 4 ms for a CEPT link
in order for the new information to be transmitted in the next
double multiframe.
