3-10 Display and Setting of Calendar Clock
The PT provides a function for displaying and setting the date and time. This sec-
tion describes the procedure for using the clock function.
Numeral Memory Table Entries Used by the Clock Function
Numeral memory table entries 247 to 255 are reserved for the display and set-
ting of the clock function.
Memory table entries 247 to 253 are for display and reading, and No. 254 and
No. 255 are for setting. (With the NT21, table entry numbers 254 and 255 are
reserved by the system.)
With the NT31/NT31C or NT631/NT631C, memory table entries 247 to 253
store the clock data that is updated according to the operation of the clock built
into the PT. The data in these memory table entries cannot be changed from the
host.
With the NT21, the clock data read from the words allocated in the host is stored
in table entry numbers 247 to 253.
