PCD6003
11 DSP I/O REGISTERS
For the DTAM application, the DSP is connected with
several peripherals as shown in Fig.21. Basically, the DSP
is connected to the analog interfaces CODEC1 and
CODEC2.
The DSP communicates with the peripherals via the
DSP I/O registers. The data transfer is performed by the
16-bit XD data bus. The I/O registers of the different
I/O units are 16 bits wide.
The microcontroller controls the DSP and is the link
between an external speech memory and the DSP. The
TICB provides the FS1 clock, which interrupts the DSP
every 125
μ
s.
11.1
Interface to CODEC
The CODEC data buffers are used to exchange speech
data between the DSP and the CODECs (see Fig.21). The
digital decimation filter DDF writes equidistant in time
16-bit linear PCM samples to the DSP I/O registers
CDC_DI0 to CDC_DI3 (address 01H to 04H for CODEC1
and address 09H to 0CH for CODEC2) at a rate of 32 kHz.
The Digital Noise Shaper (DNS) reads equidistant in time
16-bit linear PCM samples from the DSP I/O registers
CDC_DO0 to CDC_DO3 (address 05H to 08H for
CODEC1 and address 0DH to 10H for CODEC2) at a rate
of 32 kHz. The input registers CDC_DI0 to CDC_DI3 and
the output registers CDC_DO0 to CDC_DO3 are also
called data input/output DIO registers.
