R/W
8 Interrupt register.
all ‘0’
R
8 DTS[7:0]. When it is written by host all ‘0’
R/W
microprocessor, DTS[19:0] values are stored in the
DTS-FIFO.
When DTS value is received through transport
interface, it can be read via the DTS registers
8 DTS[15:8].
all ‘0’

R/W
8 Forward tolerance of DTS synchronization, h”10”
R/W
Jitter_f[7:0]. When it is written by host
microprocessor, Jitter_f[19:16] values are applied.
8 Jitter_f[15:8].

R/W
4 Jitter_f[19:16].
h“0”
R/W
8 Backward tolerance of DTS synchronization, h“BA”
R/W
Jitter_b[7:0]. When it is written by host
microprocessor, Jitter_b[19:16] values are applied.
8 Jitter_b[15:8].
h“FA”
R/W
4 Jitter_b[19:16].
h“F”
R/W
6 Slow motion command of repeated numbers.
h’8’
R/W
8 Header data register. It has header value indicated all ‘0’
R
by H_addr.
8 Header data address.
all ‘0’
R/W
8 User data register. It is an output of the User data all ‘0’
R
FIFO.
7 User data count in the User data FIFO.

R/W
8 System time clock, STC[7:0]. When it is written by all ‘0’
R/W
host microprocessor, STC[19:0] values are loaded
to internal STC counter.

value is 65,536 bits.
8 Read address pointer of the bitstream buffer. Unit all ‘0’
R
value is 65,536 bits.
8 PTS[7:0]. When PTS value is received through all ‘0’
R
tranport interface, it is stored in the PTS registers.
8 PTS[15:8].
