• Manufacturer Part Number: PEB20571
• Description: ICs for Communications
• Manufacturer: INFINEON [Infineon Technologies AG]

Note: In 1 x 16.384 Mbit/s only the first half of the frame is saved in the buffer
4.4.1.3
The D-buffer is mapped to a fixed DSP address space. Every DSP access to the D-buffer
space is directed automatically to the appropriate sub-buffer.
