4.2.4.6 Synchronous Transfer Transmit Address Register B (SAXB)
Access in demultiplexed P-interface mode:
Access in multiplexed P-interface mode:
Reset value: xx
The SAXB register specifies for synchronous transfer channel B to which output
interface, port and time slot the serial data contained in the STDB register is sent.

MTXB6..0
4.2.4.7 Synchronous Transfer Control Register (STCR)
Access in demultiplexed P-interface mode:
Access in multiplexed P-interface mode:
Reset value: 00xxxxxx
The STCR register bits are used to enable or disable the synchronous transfer utility and
to determine the sub time slot bandwidth and position if a PCM interface time slot is
involved.

Interface Select Transmit for channel B.
0… selects the PCM interface as the output interface for synchronous
1… selects the CFI interface as the output interface for synchronous
number at the interface selected by ISXB according to tables 3 and 4:
MTXB6..0 = MA6..0.
1… enables the P transfer of the corresponding channel.
0… disables the P transfer of the corresponding channel.
