5.2.18
Synchronous/address register 0 (SA0) specifies the SYN character pattern for reception in byte
synchronous mono-sync mode, the low-order eight bits of the SYN character pattern for
transmission and reception in byte synchronous bi-sync mode, and the secondary station address in
bit synchronous mode. This register is not used in asynchronous or byte synchronous external-
sync mode.
