Type Description
SEL16K 0x13[0] W Sample Rate Mode Configuration Select
Configures the 16 kHz mode of operation. See also SR.
0 = 8 kHz sampling rate. (Default)
1 = 16 kHz sampling rate.
The 16 kHz mode is enabled by setting SR=1 followed by
SEL16K=1.
SR 0x22[7] W Sampling Rate Mode
Enables the 16 kHz mode of operation. See also SEL16K.
0 = 8 kHz sampling rate. (Default)
1 = 16 kHz sampling rate.
The 16 kHz mode is enabled by setting SR=1 followed by
SEL16K=1.
TCS 0x22[2:0] W Transmit Clock Slot
Controls the starting clock of the transmit channel. The clock slot
value allows the adding of an offset of up to 7 (111) bits to the time
slot value. A value of 000 is zero offset.
TPOL 0x20[7] W Transmit Polarity
0 = The transmit PCM data is to be transmitted based on the falling
edge of PCLK. (Default)
1 = The transmit PCM data is to be transmitted based on the rising
edge of PCLK.
TTS 0x20[6:0] W Transmit Time Slot
Selects the time slot number on the PCM highway for the
transmitter. The maximum number of 8-bit time slots is 128 (with a
PCLK frequency of 8.192 MHz). A value of 0000000 is time slot
zero and 1111111 is time slot 128. The default is 0000000.
TXBST 0x14[7] WO Transmit Boost
Used in conjunction with DAA to manage transmit level. See
Section 8.8.1.
