SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using
products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd.
products described or contained herein.
SANYO Semiconductor Co.,Ltd. strives to supply high-quality high-reliability products, however, any and all
semiconductor products fail or malfunction with some probability. It is possible that these probabilistic failures or
malfunction could give rise to accidents or events that could endanger human lives, trouble that could give rise
to smoke or fire, or accidents that could cause damage to other property. When designing equipment, adopt
safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not
limited to protective circuits and error prevention circuits for safe design, redundant design, and structural
design.
Upon using the technical information or products described herein, neither warranty nor license shall be granted
with regard to intellectual property rights or any other rights of SANYO Semiconductor Co.,Ltd. or any third
party. SANYO Semiconductor Co.,Ltd. shall not be liable for any claim or suits with regard to a third party's
intellctual property rights which has resulted from the use of the technical information and products mentioned
above.
Information (including circuit diagrams and circuit parameters) herein is for example only; it is not guaranteed
for volume production.
Any and all information described or contained herein are subject to change without notice due to
product/technology improvement, etc. When designing equipment, refer to the "Delivery Specification" for the
SANYO Semiconductor Co.,Ltd. product that you intend to use.
In the event that any or all SANYO Semiconductor Co.,Ltd. products described or contained herein are
controlled under any of applicable local export control laws and regulations, such products may require the
export license from the authorities concerned in accordance with the above law.

Reed Status
RF.AGC
0: RFAGC OUT = low, 1: RFAGC OUT = high
See the separately provided documentation (application note) for details.
IF.LOCK
0: IF. PLL=Lock, 1: IF. PLL=Unlock
V.TRI
Returns the VCD internal vertical trigger detection circuit output to the bus. The internal memory state is updated on each vertical
period.
1HEX: Detected.
50/60
Returns the VCD internal 50Hz/60Hz detection circuit output to the bus.
ST/NONST
Returns the VCD standard (262.5H) or nonstandard internal vertical trigger detection circuit output to the bus. Returns the output of
the flip-flop that determines the VCD internal mode in real time.
1HEX: Standard
For more information, refer to the separately provided documentation and then contact your Sanyo representative with questions.
H.Lock
Performs a phase comparison between FBP and Hsync, integrates that output, and detects the locked state about 40H after the
horizontal VCO locks. This state is returned in real time in response to a bus read.
1HEX: Locked
KILLER
Returns the state of the color killer. Note, however, that the time constant is long and a time of roughly one vertical period (16 ms)
is required for detection. Applications must be careful concerning the wait period associated with a device state change. This state
is returned in real time in response to a bus read.
1HEX: Killer on
Color sys
Returns the color system state
See the register truth table's color system table.
The read status is the same as that for bus write.
