Explanation of RTCI data bits
1.
The HPLL increment is not evaluated by the
SAA7128H; SAA7129H.
The SAA7128H; SAA7129H generates the subcarrier
frequency from the FSCPLL increment if enabled (see
item 7).
The PAL bit indicates the line with inverted (R
Y)
component of colour difference signal.
If the reset bit is enabled (RTCE = 1; DECPH = 1;
PHRES = 00), the phase of the subcarrier is reset in
each line whenever the reset bit of RTCI input is set to
logic 1.
If the FISE bit is enabled (RTCE = 1; DECFIS = 1), the
SAA7128H; SAA7129H takes this bit instead of the
FISE bit in subaddress 61H.

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

(1) SAA7111/12 provides 14 to 0 bits, resulting in 2 reserved bits before FSCPLL increment.
(2) SAA7151 provides 21 to 0 bits only, resulting in 5 reserved bits before sequence bit.
(3) Sequence bit: PAL: 0 = (R
Y) line normal, 1 = (R
Y) line inverted; NTSC: 0 = no change.
(4) Reset bit: only from SAA7111 and SAA7112 decoder.
(5) FISE bit: 0 = 50 Hz, 1 = 60 Hz.
(6) Odd/even bit: odd_even from external.
(7) Colour detection: 0 = no colour detected, 1 = colour detected.
(8) Reserved bits: 229 with 50 Hz systems, 226 with 60 Hz systems.
