*1: In CS1G and CS1H PCs, AR 00000 to AR 00447 are read-only.
*2: The CS1G and CS1H PCs do not contain an LR Area, but LR words will be converted to CIO 01000 to CIO 01199
automatically if LR words are being used for screen data.
*3: When the EM current bank is being accessed through a Serial Communications Board or Serial Communications Unit
with 1:N NT Link (standard or high-speed), do not use elements such as touch switches that write data in bit units. An
error will occur in the PT during operation if an attempt is made to write to EM in bit units.
