4)-2. CH1 Check
Checking
If any channel is not set, the error message (ERROR: CH1) ap-
pears. When any channel is set, the following checks are per-
formed.
i. Control signal check
ERn RSn DRn
OFF OFF OFF
OFF ON OFF
ON OFF ON
ON ON ON
The program performs the read checks of the above inputs and
interrupt checks of CS, CI, and CD.
During the read check, ER and RS are changed over in the above
order, checking the logic of DR, CI, CD and CS.
If the check result does not agree with the logic in the table, the
error message appears. The ON in the table means active low
and the OFF means active high.
In the interrupt check, the CS, CI and CD interrupts are permitted
one by one (The mask is canceled.).
The error message appears if an interrupt does not occur when
each signal is active or if an interrupt occurs when each signal is
not active.
Four cycles of the above check is performed.
ii. Data transfer check
As check data, loop back data transfer of 256 bytes of 00H - 0FFH
is performed. The baud rate is 38400 bp.

iii. TIMER CHECK (RS232 ON BOARD TIMER)
Before starting the check ii, perform the RCVDT start of the timer
you want to check and set to 5 ms. Make sure::
•
No TRQ- is generated during the implementation of check ii.
•
TRQ- is generated at 5 ms after check ii is completed.
