the specific bit value is sourced from the TRAN block International/National
Control register. Depending on the settings of the TXSAxEN bits, the effective bit
rate of the data link may range between 4 bit/s and 20 kbit/s. TDLSIG is sampled
on the rising edge of TDLCLK.

When TS16 is selected as the source of the receive datalink (RXDMASIG=0 and
all of RXSAxEN=0), the 64 kbit/s TS16 data is presented on RDLSIG with an
accompanying RDLCLK with a period of 4 time slots. The data on RDLSIG is
generated on the falling edge of RDLCLK.

When TS0 is selected as the source of the receive datalink (RXDMASIG=0 and
at least one RXSAxEN bit is a logic 1), the National Use bit of TS0 of the NFAS
frames data is presented on RDLSIG with an accompanying RDLCLK. A clock
pulse is generated on RDLCLK for each National Use bit on RDLSIG which has
