I/O Word No. Bit Name Function
Output (n =
100 + 10 x
unit no.) n + 2 00 to 12 Transfer base word
No. These bits specify the PC base word (the first word
from which data is accessed) for data transfer.
13 to 15 PC memory These bits specify the section of the PC memory from which
data will be transferred between the PC and ASCII Unit with
the PC READ or PC WRITE command.

Input n + 3 00 ASCII busy This bit is used as a flag that is set during data
transfer.
(n = 100 +
10 01 to 03 --- Not used
x unit no.) 04 Port 1 error This bit is used as an error flag that is set if a
transmission error (such as parity error) has occurred
in port 1.
05 Port 2 error This bit is used as an error flag; it is set if a
transmission error (such as parity error) has occurred
in port 2.
06 Battery error This bit is used as a flag that is set when the supply
voltage of the built-in battery has dropped below the
rated level or the battery is not correctly connected.
07 BASIC RUN This flag is set while the BASIC program is running.
08 Input data These bits constitute data that is transferred from the
ASCII Unit to the PC. The data is written to the PC with
the ASCII Unit PC PUT command and is read by the
PC with the MOV.
Note: In addition to raw data, 8-bit control data can
also be transferred to the PC to facilitate branching
within the PC program.
