(7) Start Bit Detecting Circuit
This circuit detects a start bit at line decided in the data slice line
specification circuit. For start bit detection, it is possible to select one
of the following two types by using bit 1 of clock run-in register 2
(address 00E716).
After the lapse of the time corresponding to the set value of the
start bit position register (address 00E116), the first rising of the
composite video signal is detected as a start bit.
The time is set in bits 0 to 6 of the start bit position register (address
00E116) (refer to Figure 40). Set a value fit for the following
conditions.
Figure 40 shows the structure of the start bit position register.
