2—SOFTWARE
The status word is cleared during reset, and upon a successful GSW command.
The bits in the status word are used as follows:
EV_DTMF_DIGIT
DTMF digit. A value indicating a detected DTMF digit. (See the description of DTMF code in the GT com-
mand.)
EV_DTMF_END
1 = Ended detection of a DTMF tone. The detected digit is held in EV_DTMF_DIGIT.
EV_NORMAL_END
1 = Normal completion of operation, e.g., end of message playback.
EV_MEMFULL
1 = Memory is full.
EV_ERROR
1 = Error detected in the last command. You must issue the GEW command to return the error code and
clear the error condition.
EV_BUSY
1 = Busy tone detected. Use this indicator for call progress and line disconnection.
EV_DIALTONE
1 = Dial tone detected. Use this indicator for call progress and line disconnection.
EV_MEMLOW
1 = Not enough memory. (See CMSG command for further details.)
EV_CONST_NRG
1 = A period of constant energy was detected. Use this indicator for line disconnection. (See
CONST_NRG_DET_TIME_COUNT in Table 2-8.)
EV_VOX
1 = A period of silence (no energy) was detected on the telephone line. Use this indicator for line discon-
nection. (See VOX_DET_TIME_COUNT in Table 2-8.)
EV_RESET
When the VoiceDSP processor completes its power-up sequence and enters the RESET state, this bit is set
to 1, and the MWRQST signal is activated (cleared to 0). Normally, this bit changes to 0 after performing
