5.4 WRITE REGISTERS (Continued)
5.4.7 Write Register 6 (Sync Characters or
SDLC Address Field)
WR6 is programmed to contain the transmit sync charac-
ter in the Monosync mode, the first byte of a 16-bit sync
character in the External Sync mode. WR6 is not used in
asynchronous modes. In the SDLC modes, it is pro-
grammed to contain the secondary address field used to
5.4.8 Write Register 7 (SYNC Character or
SDLC Flag)
WR7 is programmed to contain the receive sync character
in the Monosync mode, a second byte (the last eight bits)
of a 16-bit sync character in the Bisync mode, or a Flag

the receive sync character or a flag if one of the special
versions of the External Sync mode is selected. WR7 is not
used in Asynchronous mode. Bit positions for WR7 are
shown in Figure 5-9.
