24-bit low-group-delay filter output will go through a high passfilter if “_hpen” bit in the Mode

output.

If more than 1 bit is set for sdata2, low-group-delay filter output will be selected for output at the

port.

Test Mode 0(address 00000100)

aoverflow

A ‘1’ indicates an overflow condition occurs in the modulator. This bit is reset by reading the

doverflow

A ‘1’ indicates an overflow condition occurs in the decimation filter. This bit is reset by reading

the register.

fir1_en(sdata)

Default = ‘0’.

Test purpose only.

fir1L_R(fir1 L channel enable)

Default = ‘0’.

Test purpose only.

_psydither(psychoacoustic filter dither disable)

Default = ‘0’.

A ‘0’ means adding dither in the psychoacoustic filter.

dstart1, dstart2(dstart control bits)

Default = ‘00’.

Test purpose only.

Test Mode 1(add 00000101)

FOR FACTORY USE ONLY

Chip Address (address 00000110)

caddr(6-0) (chip address (bit6 to bit0))

Default = ‘0000000’.

This is used to store the programmable chip address for I2C and SPI mode.

When more than 1 device are connected to the I2C or SPI buses and using chip address is nec-

essary, chip address set up is done by:

1) Hold the SDATA1 pin of every chip to ‘1’ during power up.
