Figure 2-28 SACCO-B0 Multiplexers
The SACCO-B0 can also be used as a stand-alone HDLC controller.
The I/O Port can be programmed to provide all additional support lines (DMA interface).
Different clock sources for transmit and receive data (DCLK) and for frame clock (SYNC)
can be selected by the user.
The input signal CXDB0 enables/inhibits the HDLC controller assigned to the S/T
transceiver (i.e. QUAT-S in LT-T mode); refer to Figure 2-29.
