Final outputs from pin 21/22/23 are shown in Table 2. RGB1-IN interface complies with SCART connector. Therefore it is active, when RGB1-IN is enable by the BUS data and when YS3 (pin 15) is also high. The status of YS3 (pin 15) is responded to the Read BUS data, V15.

The demodulated color system is responded to the read BUS data, COLOR SYSTEM and X’TAL. (refer to BUS CONTROL FUNCTION) The system data is also responded to Comb SYS (pin 45) and fsc-OUT (pin 46) as Table 3. If distinguishable color system signal is not received, the system data is responded with B/W. Besides, if pin 7 is connected to VCC (more than 3.5 V), Forced SECAM mode is active. In this mode, SECAM system is identified forcibly. It has priority over the BUS selection.

In Fast mode, it is synchronized with the inputted synchronizing signal and the pull-in time is short. Furthermore the time is shorter in Very fast mode by the expanded pull-in range. Pull-in range of vertical count-down is determined by the BUS data, V C/D MODE and V-FREQ as Table 4. Table 4 V C/D Mode V C/D FREQ V C/D Pull-In Range Normal Teletext Fast 00, 11 01 10 000 Automatic 1 224-353 H 224-353 H 32-353 H 001 50 Hz 274-353 H 274-353 H 32-353 H 010 60 Hz 224-297 H 224-297 H 32-297 H 011 Automatic 2 224-353 H 224-353 H 32-353 H 100 312.5 H Forced 312.5 H mode&AFC free-run 101 262.5 H Forced 262.5 H mode&AFC free-run 110 313 H Forced 313 H mode&AFC free-run 111 263 H Forced 263 H mode&AFC free-run Note 3: 00, 11; Normal Normal vertical input mode. It is good performance of vertical phase keeping for standard TV signal sync. This mode is recommended in the state of stability. And this mode can detect teletext or VCR skew sync. Note 4: 01; Teletext This mode is less performance of vertical phase keeping for standard TV signal sync against “Normal”. However, pull-in speed is faster few vertical periods than “Normal”. Therefore this mode is recommended for tesetext sync. On the other hand, this mode can detect standard TV signal sync in the state of stability but it is less performance of vertical phase keeping in week signal as about -3 dB against “Normal”. Note 5: 10; Fast This mode is same performance of vertical phase keeping for standard TV signal sync of “Teletext”. But it is faster pull-in speed faster than “Teletext” because pull-in ranges wider than “Teletext”. (refer to Table 5) Therefore, this mode is better to use when channel changing, but is not recommended to use in the state of stability or in week signal due to too wide pull-in range and incorrect actions of vertical keeping appearing. Y-DL Adjustment Table 5 shows Y output delays against Y input on condition with BPF = f0, Q = 2.0, Y-DL = Min and LPF = ON. Y-out signal can be delayed by the BUS data, Y-DL. The adjustment time of one step is 40 ns.
