3) HL00 + 0042 to 5, HL00 + 0142 to 5: I/O setting
It sets the I/O assignment of the S-LINK V I/O units.
Just after power ON / reset of the computer, it indicates the setting condition of "4) I/O setting
switch (For port 1: SW1 / SW2, For port 2: SW4 / SW5)" in "4. Functional Description."
When setting is done by a program, I/Os can be set in units of 16. In this case, set all the I/O set-
ting switches to input ("0": ON). (If the change is done by program, it is automatically changed
within 1 to 2 refresh times.)

Error states
(UURU RFFXUUHQFH 1RUPDO RSHUDWLRQ HUURU UHFWL¿HG
bit 0 to 3 : Occurred error No. is displayed. (0H to 6H)
bit 7
: The error state is indicated.
Notes: 1) Error 0 is not automatically restored. (In case bit 7 is "1" and bit 0 to 3 is "0H," Error "0" occurs.)
2) If Error 1, 2, and 3 to 6 occur at the same time, Error 1 and 2 are given priority in error indication.
3) For Error 1 to 6, in case the cause of the error is eliminated, although bit "7" becomes "0," the error
No. indication of bit 0 to 3 is maintained.
4) Even if write into HL00 + 004B and HL00 + 014B, it is ignored.
