This
HEAD[23:16].HEAD3[7:5]=“000”,
HEAD3[4:0] = DTYPE
DTYPE is the data type and is defined as follows:
This register can not detect the data-type of data in a stream.
HEADLEN
Frame length
Addres s: 0x44 - 0x45
Type: RO
Software Reset: UND
Hardware Reset: UND
Description:
The HEADLEN register contains the bit length of the
compressed data frame HEAD[15:0]. HEADER reg-
isters are all updated as soon as the decoder begins
to decode a frame.

Description:
When the PTS interrupt is activated, a new PTS val-
ue is stored in this register. Once the PTS[32] value
is read bit PTS of the PTS register is cleared.

Description:
This is a status register, when read by the ST20, this
and the corresponding interrupt register are cleared.
This 7-bit register is ANDed with 0x7F to get the cor-
rect value. The value in the ERROR register indi-
cates the type of error that has occurred. These
errors are defined in the table below.
