5-4-2 Notification of Character String to the PC
Numeral and Character String Setting
This section describes how the character string data input at an NT30/30C is ac-
cessed by the PC.
In order to determine when character string data has been input at the
NT30/30C, the character string setting strobe flag in the PT Status Notify Area is
used. In order to determine the upgraded character string memory table entry
number, the content upgrade memory table entry in the PT Status Notify Area is
used.
When character string 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.
When the PC reads the content upgrade memory table entry at the leading edge
of the character string setting strobe flag, it determines the character string
memory table entry number in which the character string data that was changed
at the NT30/30C is stored.
Content Upgrade Memory Table Entry Set in the PT Status Notify Area and PT
Status
Data is written to the content upgrade memory table entry as three digits of BCD
(binary coded decimal) data.
When the character string setting strobe flag bit has been notified to the PC it
returns to the OFF (0) status.
For details on the method for storing a number in a word allocated for the charac-
ter string table entry, see Allocation Words and Display of the Memory Tables
(page 205).
