Synchronous Transfer Transmit
Address Register B
SAXB:
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.

Synchronous Transfer Control
Register STCR
STCR:
The STCR register bits are used to enable or disable the synchronous transfer utility and
to determine the subtime slot bandwidth and position if a PCM interface time slot is
involved.

Interface Select Transmit for channel B; selects the PCM interface
(ISXB = 0) or the CFI (ISXB = 1) as the output interface for
synchronous channel B.
slot number at the interface selected by ISXB according to figure 48:
MTXB6 … 0 = MA6 … 0.
Transfer Channel A (B) Enable; A logical 1 enables the P transfer, a
logical 0 disables the transfer of the corresponding channel.
Channel Type A (B); these bits determine the bandwidth of the
channel and the position of the relevant bits in the time slot according
to table 33. Note that if a CFI time slot is selected as receive or
transmit time slot of the synchronous transfer, the 64 kbit/s bandwidth
must be selected (CT#2 … CT#0 = 001).
P Transfer Transmit Address for channel B; selects the port and time
