Name
Status Flag Set
Status Flag Cleared
Interrupt has occurred. Bi tone (b1) and/or bit 2 (b2)
is set.
Pause duration has terminated and transmitter is
ready for new data.
Valid data is in the receive data register.
Interrupt is inactive. Cleared after status register is
read.
Cleared after status register is read or when not in
burst mode.
Cleared after status register is read.
b1 Transmit data register
empty (burst mode only)
b2 Receive data register
full
b3 Delayed steering
Set on valid detection of the absence of a DTMF sig-
nal.
Cleared on detection of a valid DTMF signal.
