GSM baseband procedures
The baseband procedures with optional input parameters can be called by the EXEC_PROC command as described in
Section 9.2. Return values are packed in the PROC_RETURN indication. Every procedure deals with the following types
of data:
Input parameters which are directly supplied by the System Controller
Return values which are automatically sent to the System Controller as soon as the procedure is completed
Input and output data buffers located in the DSP data RAM. They are used for communication with other procedures.
Most of the procedures use a common buffer SCRATCH_BUFF for their input and output data. Only a small number
of procedures need specific buffer for input or output. In this case there are one or two additional parameters in_buff_id
or out_buff_id which determine the buffers where input and output data are located. In Table 55 a list of all available
buffers is given.
For all trailing parameters of a procedure which are not transmitted with the EXEC_PROC command a default value of
zero is used.

Contains the BCD coded version numbers of all software packages (order:
MP, BB, CI, CM, DB, EM, FB, SP and TP). A version number 0Xmm.ss
means version mm.ss.
Scratch buffer for communication between arbitrary modules.
The combination of the 4 buffers; TCH_CMI_BUFF1 to TCH_CMI_BUFF4.
Used to store the CMI values of 4 consecutive bursts belonging to one TCH
block.

Used to store four normal bursts during TCH loop-back operation. Note this
buffer is also used by the speech encoder.
Used to control several features of the firmware; see Table 56.
Used to store I and Q components from the PCF5072. This buffer is
overlaid with SCRATCH_BUFF.
