This section describes how the numerical data input at an NT30/30C is accessed
by the PC using the numeral setting function (numeral input function).
In order to determine when numerical data has been input at the NT30/30C, the
numeral setting strobe flag in the PT Status Notify Area is used. In order to deter-
mine the upgraded numeral memory table entry number, the content upgrade
memory table entry in the PT Status Notify Area is used.
When numerical data is input at the NT30/30C, this is automatically notified to the
PT Status Notify Area (PT → PC) allocated in the PC memory as follows.
Notification of upgrade:
Upgraded numeral table entry number:
When the PC reads the content upgrade memory table entry at the leading edge
of the numeral setting strobe flag, it determines the numeral memory table entry
number in which the numerical data that was changed at the NT30/30C is
stored.
