BIT
NAME
STATUS FLAG SET
STATUS FLAG CLEARED
b0
IRQ
Interrupt has occurred. Bit one
(b1) or bit two (b2) is set.
Interrupt is inactive. Cleared after
Status Register is read.
b1
TRANSMIT DATA
REGISTER EMPTY
(BURST MODE ONLY)
Pause duration has terminated
and transmitter is ready for new
data.
Cleared after Status Register is
read or when in non-burst mode.
b2
RECEIVE DATA REGISTER
FULL
Valid data is in the Receive Data
Register.
Cleared after Status Register is
read.
b3
DELAYED STEERING
Set upon the valid detection of
the absence of a DTMF signal.
Cleared upon the detection of a
valid DTMF signal.

* Microprocessor based systems can inject undesirable noise into the supply rails.
The performance of the MT8889C/MT8889C-1 can be optimized by keeping
noise on the supply rails to a minimum. The decoupling capacitor (C3) should be
connected close to the device and ground loops should be avoided.
