TGCR
ET
0: Tone generator is disabled
1: Tone generator is enabled; frequency and gain coefficients loaded from CRAM
DT
0: Dual tone mode is disabled
1: Dual tone mode is enabled; the output of signal generator FD is added to the tone
ETF
0: Tone filter is by-passed
1: Tone filter is enabled; filter coefficients loaded from CRAM
PT
0: Pulsed tone is disabled
1: Pulsed tone is enabled; time coefficients loaded from CRAM
SEQ
0: Sequence generator is disabled, a continuous tone signal is generated
1: Sequence generator is enabled; time coefficients loaded from CRAM
TM
0: Two-tone sequence is activated when sequence generator is enabled with SEQ = ’1’
1: Three-tone sequence is activated when sequence generator is enabled with SEQ =
signal which is determined by TM and SEQ;
dual tone mode is only available if TGSR.DTMF = ’0’
otherwise a continuous signal (F1, G1) is generated
’1’ otherwise a continuous signal (F2, G2) is generated;
three-tone sequence is only available if TGSR.DTMF = ’0’
