Since Nch open drain is used,
external pull-up is required.
CD EH mechanism
detection switch
MIC detection and DSTB port replacement
DSTB input must be through INTP6 interruption port.
P06->INTP6; MIC detection -> (MD)DST
Change to input port
P23; (MD)DSTB Change to MIC detection input
P131; Naming is changed to illumination ON/OFF
switching
P130: Illumination output port in OFF state ->
Change to SD input port
P72; Not used -> To be used as output port of
(MD)V.LOAD. Function is added.
P54; SD input -> Function is added as FAN MOTOR
output.
P55; Not used -> To be used as (MD) P.DOWN
output port. Function is added.
