(3) Coincidence detection point setting (Un\G6 and 7)
Coincidence detection point change request (Un\G8)
• Write the coincidence detection point setting value to be compared with the
present value A (Un\G10 and 11)/counter present value B (Un\G200 and 201) for
counter.
• When 1 (Change request) is written to the coincidence detection point change
request (Un\G8), the value written to the coincidence detection point setting
(Un\G6 and 7) becomes effective, the QD63P6 writes 0 (No change request) to
the coincidence detection point change request (Un\G8), and then the
coincidence detection point setting is started.
• Setting range of the coincidence detection point setting (Un\G6 and 7) is from
-2147483648 to 2147483647 (32-bit signed binary).
• If 1 (Change request) is not written into the coincidence detection point change
request (Un\G8), the coincidence detection point setting value (Un\G6 and 7)
does not become effective.
• If 1 (Change request) is not written, the setting is not reflected.

and coincidence detection point change request (Un\G8)
• For details of the general operation, refer to Section 5.3.
