Transmit Path Control Register
Receive Path Control Register
Control bits b0 to b3 are used to configure the transmit path and select the transmit source. Note that for SSI mode all selections where
b3 = 1 are not used and are interpreted as b0 - b3 = 0 (i.e., transmit path off).
Control bits b0 to b7 are used to assign a signal source individually to each receive path output. In addition transmit to receive voice
sidetone path control is included.
