All buttons are judged with the voltage of A/D port. The reference
voltage of A/D port is EVER +3.3 V. To reject chattering,
measure the voltage twice and the same values are obtained, this
voltage is judged as the A/D port voltage. The dead zone is
provided for the IF CON button judgment voltage. When a
voltage within the range of dead zone is input, “IGNORE” is
displayed.

The IF CON and SYSTEM CONTROL are usually performing
both-directions communication in a cycle of 24 ms. This mode
checks in simple whether this communication is performed
normally. When “NOTHING” is displayed and the character

checks in simple whether this communication is performed
normally. When “NOTHING” is displayed and the character
portion of
[VCR]
,
[DVD]
and

has gone out on the left side
of the display, this state means that communication with
SYSTEM CONTROL is performed normally. If the character
portion is lit up, this state means the communication is not
performed correctly. After the test mode is executed (until
initialization of the MB-89 board is completed), communication
is not performed for several seconds. Although the character
portion may light up in these intervals, but this is normal.
