QUICC1 and QUICC2 exchange transparent frames and synchronize each other using the
RTS and CD pins. The CTS pin is not required since transmission may begin at any time.
Thus, the RTS signal is directly connected to the other QUICC’s CD pin. The RSYN option
in GSMR is not used, and transmission and reception from each QUICC are independent.
7.10.21.5 TRANSPARENT MEMORY MAP. When configured to operate in transparent
mode, the QUICC overlays the structure listed in Table 7-5 onto the protocol-specific area
of the SCC parameter RAM listed in Table 7-10.
