Preliminary
Precautionmustbetakenduring Burst-modeoperation:
DTMF pin will output 1/2 VDD during next burst-cycle
if the user does not initialize the TC~TR value again.
When the burst-cycles starts, if the user clears the
BURST flag to 0 before Step 2 is finished, Step 3 and
Step 4 will be executed and after step 4 is executed,
DTMF output mode will be changed to Tone-Mode.
When the burst-cycle starts, if the user clears the
BURST flag to 0 after Step 3 is executed, then Step 4
and Step 5 will be executed. After next Step 4 is exe-
cuted, DTMF output mode will be changed to
Tone-Mode.
When the burst-cycles starts, if the user clears the
TONE flag to 0, DTMF output will be changed to 1/2
VDD.
When the burst-cycle starts, if the user changes the
TC~TR value at Step1, DTMF pin output will also be
changed (determined by the new TR~TC value). The
DTMF output duration of burst-cycle is constantly
82.5ms.
When the burst-cycle starts, if the user changes the
TC~TR value at Step2, DTMF pin still outputs 1/2
VDD. The DTMF output duration of burst-cycle is con-
stantly 85.5ms.
If the next burst-cycle is executed continuously, Step
4 and Step 5 occur simultaneously.
