Tx/Rx Low Pass Filter Delay
The previous task timing figures are based on the signal at the input to the Tx Low Pass filter (in
transmit mode) or the input to the de-interleave buffer (in receive mode). There is an additional delay
of about 2 bit times in both transmit and receive modes due to the Tx/Rx Low Pass filter, as
illustrated in Figure 11.

Control Register
This 8-bit write only register controls the modem's bit rate, the response times of the receive clock
extraction and signal level measurement circuits and the internal analogue filters.
