POINT
When "1: Valid" is set in "
", the response time of the high-speed input signal is compensated and the
setting
latch accuracy will be enhanced.

(Note): Refer to the table of "Performance specifications" in this section for the range of mark
detection setting No. that can be used for each module.
• Guide to buffer memory address
In the buffer memory address, "k" in "54002+20k", etc. indicates a value
corresponding to mark detection setting No. such as the following table.

(Note): Refer to the table of "Performance specifications" in this section for the range of mark
detection setting No. that can be used for each module.
(Note): Calculate as follows for the buffer memory address corresponding to each mark detection
setting No.
(Example) For mark detection setting 16
54002+20k (
(Note): The range from mark detection setting No.1 to 4 (k=0 to 3) is valid in the
LD77MS2/LD77MS4.
