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. E.g. time slot 32 can be
accessed at address 0xA020 in receive and 0xA0A0 in transmit direction.
