Fig. 31. Structure of clock run-in register 3
For the main data slice line, the count value of pulses in the window
is stored in clock run-in register 1 (address 00E6
16
; refer to Figure
30). For the sub-data slice line, the count value of pulses in the window
is stored in clock run-in register 3 (address 0209
16
; refer to Figure
29). When this count value is 4 to 6, it is determined as a clock run-in.
Accordingly, set the count value so that the window may start after
the first pulse of the clock run-in (refer to Figure 32).
The contents to be set in the window register are written at a falling
of the horizontal synchronizing signal. For this reason, even if an
instruction for setting is executed, the contents of the register cannot
be rewritten until a falling of the horizontal synchronizing signal.
For the main data slice line, reference clock is counted in the period
from a falling of the clock pulse set in bits 0 to 2 of the clock run-in
detect register 2 (address 00E9
16
) to the next falling. The count value
is stored in bits 3 to 7 of the clock run-in detect register 1 (address
00E8
16
) (When the count value exceeds “1F
16
,” “1F
16
” is held). For
the sub-data slice line, the count value is stored in bits 3 to 7 of the
clock run-in detect register 3 (address 0208
16
). Read out these bits
after the occurence of a data slicer interrupt (refer to (11) Interrupt
Request Generating Circuit).
Figure 33 shows the structure of clock run-in detect registers 1 and
3.
