TPA/B = These two bits are used to enable the DX outputs of the port A or/and B. According to the combination
of these two bits the enabled port will be as follows:
RPAB = 0: Port A enabled (DRA input selected)
RPAB = 1: Port B enabled (DRB input selected)
TE = 0: Transmit PCM data change on rising edge of MCLK
TE = 1: Transmit PCM data change on falling edge of MCLK
PC1-PC0 = Selection of the channel for the PCM access data via MCU.
WR = 1: Setting this bit , receive PCM data writing via MCU (after A/
μ
decoding) is enabled on selected channel
and IPCM interrupt is generated every time FS signal becomes active, together to the set of the WRD bit in the
PCMCTRL register.
A data byte must be written every 125
μ
s, if data is not replaced the old value is inserted again but the PMW bit
is set to 1 in the PCMCTRL register.
RR = 1: Setting this bit, transmit PCM data reading (after A/
μ
encoding) via MCU is enabled on selected channel
and IPCM interrupt is generated every time that data are available, together to the set of the RRD bit in the PC-
MCTRL register.
A data byte must be read every 125
μ
S, if data is not read the new value is written in the PCM access register
but the POW bit is set to 1 in the PCMCTRL register.
Transmit Time Slot ch #0 (DXTS0)
Addr=52h; Reset Value=00h
EN0=0:Selected transmit time slot on DX output is in H.I.
EN0=1:Selected transmit time slot on DX output is active carrying out the PCM encoded signal of VFXI0.
T06..0:Define time slot number (0 to 127) on which PCM encoded signal of VFXI0 is carried out.
If linear mode is selected (LIN=1 of CONF register) the 16 bits will be carried out as follows: the 8 most signifi-
cant bits in the programmed time slot, the 8 least significant bits in the following time slot.
Example: if T06..T00=00:
