• Manufacturer: SIEMENS [Siemens Semiconductor Group]

Access in multiplexed P-interface mode:
Access in multiplexed P-interface mode:
4.2.4
4.2.4.1 Synchronous Transfer Data Register (STDA)
Access in demultiplexed P-interface mode:
Reset value: xx
The STDA register buffers the data transferred over the synchronous transfer channel A.
MTDA7 to MTDA0 hold the bits 7 to 0 of the respective time slot. MTDA7 (MSB) is the
bit transmitted/received first, MTDA0 (LSB) the bit transmitted/received last over the
serial interface.
4.2.4.2 Synchronous Transfer Data Register B (STDB)
Access in demultiplexed P-interface mode:
Reset value: xx
The STDB register buffers the data transferred over the synchronous transfer channel B.
MTDB7 to MTDB0 hold the bits 7 to 0 of the respective time slot. MTDB7 (MSB) is the
bit transmitted/received first, MTDB0 (LSB) the bit transmitted/received last over the
serial interface.
