1. Device key address.
2. H-W registers address.
3. H-W parameters address.
4. Determines the clock direction (Rx or Tx) and the baud rate
5. Determines the work mode — HDLC or UART.
6. Determines the HDLC flags.
7. The events that generate the interrupt.
8. Mask to block the interrupt.
9. The CM (Channel Monitor) and TD (Tone Detect) statuses.
10. How many idles to wait before declaring that the transmission has ended.
11. The actual counter that counts the number of idles since the last character was received. For example,
the time that a character takes to arrive (corresponds to idle) at 9600 baud is 1 msec.
