µP Mode
Test modes Send Single Pulses, Quiet Mode or Data Through are invoked via the
corresponding C/I Channel command (see "C/I Channel Codes", page 224) or via bits
STCR:TM2,TM1 (Table 4). See also "STCR-Register", page 212.
Stand-Alone Mode
The test modes Send Single Pulses (SSP), Quiet Mode (QM) and Data Through (DT)
are invoked via the corresponding C/I Channel command ("C/I Channel Codes", page
224) or via pins RES and TSP (Table 4).
