8.10.11 16-bit Shift Register
The caption data converted into a digital value by the comparator is
stored into the 16-bit shift register in synchronization with the data
clock. The contents of the high-order 8 bits of the stored caption data
can be obtained by reading out data register 2 (address 00E3
16
) and
data register 4 (address 00CF
16
). The contents of the low-order 8
bits can be obtained by reading out data register 1 (address 00E2
16
)
and data register 3 (address 00CE
16
), respectively. These registers
are reset to “0” at a falling edge of V
sep
. Read out data registers 1
and 2 after the occurrence of a data slicer interrupt (refer to “8.10.12
Interrupt Request Generating Circuit”).
8.10.12 Interrupt Request Generating Circuit
The interrupt requests as shown in Table 8.10.3 are generated by a
combination of the following bits; bits 6 and 7 of the caption position
register (address 00E6
16
). Read out the contents of data registers 1
to 4 and the contents of bits 3 to 7 of the clock run-in detect register
after the occurrence of a data slicer interrupt request.
