GSM signal processing IC
PCF5083
The MP_CONTROL_BUFF may be used to control several features of the DSP. It consists of 4 parameter fields as given
in Tables 56 and 57.
Table 56 Contents of MP_CONTROL_BUFF
Table 57 Associated I/O pins
Note
1. If proc_trace_buff[1] is 0, then IO3 is set on errors.

DESCRIPTION
0
time-out_freq: ECLK input frequency divided by 10 kHz. After reset time-out_freq is set to
3 (32.768 kHz clock).
1
eclk_cycle_count: contains number of ECLK cycles spent most recently called procedure. Required for
test purposes only.
2 to 4
proc_trace_buff[2]: for debugging purposes the DSP provides a procedure trace facility. The IDs of the
procedures to be traced must be stored in proc_trace_buff. If any of these procedures is executing, its
corresponding I/O pin (see Table 57) is set to a logic 0.
