Hardware Reset: 0x01

The REQ_POL registers is used to program the

polarity of the DATA_REQ line.

MSB

LSB

000000

Default polarity (the source sends data when the

DATA_REQ line is high)

MSB

LSB

000001

Inverted polarity (the source sends data when the

DATA_REQ line is low)

SCKL_POL is used to select the working polarity

of the Input Serial Clock (SCKR).

(1) If SCKL_POL is set to 0x00, the data (SDI)

are sent with the falling edge of SCKR

and sampled on the rising edge.

(2) If SCKL_POL is set to 0x04, the data (SDI)

are sent with the rising edge of SCKR and

sampled on the falling edge.

When this register is written, a soft reset occours.

The STA013 core command register and the in-

terrupt register are cleared. The decoder goes in

to idle mode.

The PLAY command is handled according to the

state of the decoder, as described in section 2.5.

PLAY only becomes active when the decoder is

in DECODE mode.
