Bit Name
Bit Name
In Transmit Clock Slave mode and Transmit Multiplexed mode, these 2 bits select the T1/J1 to E1 format mapping schemes.
In Transmit Non-multiplexed mode, this bit selects the sub-mode.
= 0: The Transmit System Interface is operated in Transmit Clock Master mode. The timing signal for clocking the data and the framing pulse to
align the data input on the TSDn pin are provided from the processed data from the device.
= 1: The Transmit System Interface is operated in Transmit Clock Slave mode. The timing signal for clocking the data and the framing pulse to align
the data input on the TSDn pin are provided by the system side.
These bits give a binary number to define the channel offset. The channel offset is between the framing pulse on the TSFSn/MTSFS pin and the
In Non-multiplexed mode, the channel offset can be configured from 0 to 23 channels (0 & 23 are included). In Multiplexed mode, the channel
