EPSON
Connect the RES terminal to the MPU reset terminal as
described in “6-1 MPU Interface”, and execute
initialization simultaneously with the MPU. However, if
the MPU bus and port are put into HIGH impedance for
a certain time period by resetting, perform reset input to
the S1D12205 Series after the input to the S1D12205
Series has been determined. When the RES terminal
becomes LOW, each register is cleared and the above
setup is established. If initialization by the RES terminal
is not performed when power voltage is applied, resetting
may be disabled.
