If an attempt to write to these bits, write “0.” The read turns out to be “0.”

Nothing is assigned.

2.14.11 Caption Register and CRCC Data Register

The caption data converted into a digital value by the comparator is stored into the caption register and

CRCC data register in synchronization with the data clock. The contents of the stored caption data can be

obtained by reading out the caption data register and CRCC data register. These registers are reset to “0”

at a falling of Vsep. Read out these registers after the occurrence of a data slicer interrupt (refer to

“2.14.12 Interrupt request generating circuit)”.

Caption data 1L

The following data is stored in 026616, and the 030616

street of bits 7 and 6.

In the case of CC caption

b7, b6

Data 16-9 of CC21 is stored in bit 7-0.

Data 16-9 of CCX is stored in bit 7-0.

Data 16-9 of CC21 is stored in bit 7-0.

In the case of ID1 caption

b7, b6

Data 16-9 of CC21 is stored in bit 7-0.

Data 14-7 of ID1 is stored in bit 7-0(*).

Data 16-9 of CC21 is stored in bit 7-0.

Do not set.
