Transmitter Data Buffer. Contains the byte to be transmitted in the parallel mode.
Transmitter Data Buffer Empty. Reports the status (empty or not empty) of the Transmit
Data Buffer (TBUFFER). (See TDBIE and TDBIA.)
Transmitter Data Buffer Interrupt Active. Reports that the cause of an interrupt request
Is the Transmit Data Buffer (TBUFFER) empty. (See TDBE and TDBIE.)
Transmitter Data Buffer interrupt Enable. Enables assertion of IRQ and the setting of the
TDBIA bit when the TBUFFER is empty. (See TDBE and TDBIA.)
Transmit Level Attenuation Select. Selects the transmitter analog output level
attenuation In 1 dB steps. The host can fine tune the transmit level to a value lying within
a 1 dB step In DSP RAM.
Test Mode. Reports active status of the selected test mode.
Tone Filter A Energy Detected. Reports status of energy above the threshold detection
by the Call Progress Monitor filter in the Dial Configuration or 1300 Hz FSK tone energy
detection by the Tone A bandpass filter In the Tone Detector configuration.
Tone Filter B Energy Detected. Reports status of 390 Hz FSK tone energy detection by
the Tone B bandpass filter in the Tone Detector configuration.
Tone Filter C Energy Detected. Reports status of 1650 Hz or 980 Hz (selected by the
ORG bit) FSK tone energy detection by the Tone C bandpass filter in the Tone Detector
configuration.
Transmitter Parallel Data Mode. Selects transmitter parallel or serial mode.
Timing Recovery Freeze. Inhibits the update of the receiver’s timing recovery algorithm.
Transmit Clock Select. Selects the transmitter data clock (internal, disable, slave, or
external).
Transmit Parity Bit (or 9th Data Bit). This bit Is the stuffed parity bit (or ninth data bit)
for transmission.
Transmitter Squelch. Disables transmission of energy.
Transmit Voice. Enables the sending of voice samples.
Unscrambled Ones Detected. Reports detection status of the Unscrambled Ones
sequence.
Data Word Size. Selects the number of data bits per character in asynchronous mode (5,
6, 7. or 8).
Volume Control. Two-bit encoded speaker volume selects volume off or one of three
volume on levels.
X RAM Access Enable. Controls DSP access of the X RAM associated with the address
in XADD and the XCR bit. XWT determines it a read or write is performed.
X RAM Address. Contains the X RAM address used to access the DSP’s X Data RAM or X
Coefficient RAM (selected by XCR) via the X RAM Data LSB and MSB registers.
