receive direction different system clocks and system pulses are necessary. The interface
to the receive system highway is realized by two data buses, one for the data RDO and
one for the signaling data RSIG. The receive highway is clocked on pin SCLKR, while
the interface to the transmit system highway is independently clocked on pin SCLKX.
The
2.048/4.096/8.192/16.384/1.544/3.088/6.192/12.352 Mbit/s for the receive and transmit
system interface is programmable by SIC1.SSC1/0, SIC2.SSC2 and SIC1.SSD1,
FMR1.SSD0. Selectable system clock and data rates and their valid combinations are
shown in the table below.
