Explanation of RTCI data bits
1.
The HPLL increment is not evaluated by the
SAF7129AH.
The SAF7129AH 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
SAF7129AH takes this bit instead of the FISE bit in
subaddress 61H.

Iftheodd/evenbitisenabled(RTCE = 1;DECOE = 1),
the SAF7129AH ignores its 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 SAF7129AH. 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) SAF7113 and SAF7118 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) Colour detection: 0 = no colour detected, 1 = colour detected.
(6) Reserved bits: 229 with 50 Hz systems, 226 with 60 Hz systems.
