Writing to this register provides the transmit data when the transmit switch channel is configured to use parallel microprocessor data as its source (to
CT_D). This register and the serial input buffer share common hardware, therefore this register must be written after the transmit switch channel
source is changed from serial TDM data to parallel microprocessor data.
The transmit switch channel output buffer data obtained by reading the TDM data register. When the transmit switch channel is configured to use serial
TDM data as its source, the data from the local SI channel can be monitored. When the transmit switch channel is configured to use parallel
microprocessor data as its source, the data written into this register can be monitored.
Note: When converted from parallel to serial, TDM Data Bit 1 is transmitted first.

Writing to this register provides the receive data when the receive switch channel is configured to use parallel microprocessor data as its source (to
L_SO). This register and the serial input buffer share common hardware, so this register must be written after the receive switch channel source is
changed from serial TDM data to parallel microprocessor data.
The receive switch channel output buffer data is obtained by reading the TDM Data register. When the receive switch channel is configured to use serial
TDM data as its source, the data from the CT_D stream and time-slot selected in the receive switch routing registers can be monitored. When the
receive switch channel is configured to use parallel microprocessor data as its source, the data written into this register can be monitored.
Note: When converted from parallel to serial, TDM Data Bit 1 is transmitted first.
