Program operation
When the program is executed, the operation is as follows.
(1) When bit 00000 comes ON, the contents (“minute”) of numeral memory
table 248, which is used for reading the clock function, are copied to numeral
memory table 258.
(2) After waiting about a second for the memory table copy operation in step (1)
to be completed, copy the contents of numeral memory table 249 (“hour”),
which used for reading the clock function, into numeral memory table 259.
The hour and minute set in the NT620S/620C are stored in DM0000 and
DM0001, which are the words allocated to numeral memory tables 258 and
259.
