FUNCTIONAL DESCRIPTIONS
The MPU Interface
Selecting the interface Type
The EM65565A chip can be selected either parallel interface or serial interface by the
P/S terminal polarity to the “H” or “L”, as shown in Table 2

“--“Indicates fixed to either “H” or to “L”
The Parallel Interface:
When the parallel interface has been selected (P/S=”H”), then it is possible to connect
directly to either an 80-series MPU or a 68-series MPU by selecting the MPUS terminal to
either “H” or to “L”.

The Serial Interface:
When the chip is active state (/CS1=”L” and CS2=”H”) the serial data input (SI) and the
serial clock input (SCL) can be received. The serial data is read from the SI pin in the rising
edge of the serial clocks D7, D6 through D0, in this order. This data is converted to 8 bits
parallel data in the rising edge of the 8th serial clock for the processing.
The D/I input is used to determine whether or the serial data input is display data (D/I=”H”)
or command data (D/I=”L”). The D/I input is read and used for detection every 8th rising edge
of the serial clock after the chip becomes active. Figure 2 is a serial interface signal chart.
