The RSC interrupt can be suppressed for cleared channels to reduce the interrupt load.
Suppression mode is selected by CCR1.RSCC = 1.

In T1/J1 ESF mode the DL-bit access is improved to reduce the number of required
register accesses by 25%. For details see
is selected by the new register bit FMR5.DLM. The transmit direction works accordingly.
BOM-Codes can be inserted continuously without additional microcontroller access
every multiframe.
The BOM code has the following format: 11111111 0xxxxxx0 were the left bit here of
every byte is the MSB and the right one is the LSB. (11111111 is the BOM flag, xxxxxx
is the BOM code) That´s another ordering as in ANSI T1.403, 1999, table 4 !!. Sending
is done as for HDLC: LSB first. That´s consistent to the note 1) in the ANSI: “rightmost
bit transmitted first”.
