Fig 22. RTCI timing
RTCI
(1) SAA7113 and SAA7118 support RTC level 3.1.
(2) Sequence bit: PAL: 0 = (R Y) line normal, 1 = (R Y) line inverted; NTSC: 0 = no change.
(3) FISE bit: 0 = 50 Hz, 1 = 60 Hz.
(4) Odd/even bit: odd_even from external.
(5) Color detection: 0 = no color detected, 1 = color detected.
(6) Reserved bits: 229 with 50 Hz systems, 226 with 60 Hz systems.

If the odd/even bit is enabled (RTCE = 1; DECOE = 1), the SAA7128H; SAA7129H
ignores its internally generated odd/even flag and takes the odd/even bit from RTCI
input.
If the color detection bit is enabled (RTCE = 1; DECCOL = 1) and no color was
detected (color detection bit = 0), the subcarrier frequency is generated by the
SAA7128H; SAA7129H. In the other case (color detection bit = 1) the subcarrier
frequency is evaluated out of FSCPLL increment.
If the color detection bit is disabled (RTCE = 1; DECCOL = 0), the subcarrier
frequency is evaluated out of FSCPLL increment, independent of the color detection
bit of RTCI input.
