Description:
This version register is read only and is used to iden-
tify the audio hardware version. The version register
holds a number which refers to the cut number. The
version numbers are defined as below:
9.4 SETUP & INPUT REGISTERS
The STA310 can get receive an input bitstream either
from the I2s input or ffrom the Spdif input, the selec-
tion and the configuration is done through 2 registers
SIN_SETUP @ 12 and CAN_SETUP @ 13.

Description:
This register is used to configure the input data inter-
face. The register must be setup before sending data
to the IC. The mapping of the register isescribed be-
low. Remember that the data must be sent to the de-
vice MSB first.
The configuration of the 3 possible interfaces is

When the IC is configured in mode 1 or 3, the
CAN_SETUP register is used to configure the IC with
repect to the data format.
CAN_SETUP

Software Reset: NC
Hardware Reset: 0
Description:
CAN_SETUP is used to configure the data serial in-
terface. The register is only taken into account when
the register sin_setup [1...0] = 3.
Also see SIN_SETUP register./
When the IC is configured with the S/PDIF input, reg-
ister CAN_SETUP must be set to 2
