FUNCTION DESCRIPTION
SYSTEM INTERFACE
Figure 2
MPU interface
The EPL43102 has two chip select pin /CS1 and CS2. In case of /CS1="L" and CS2=”H”,
the interface with MPU is available. When the chip select pin is inactive (Other /CS1 and
CS2 condition), D7 to D0 are high impedance (invalid) and input of A0, /RD, or /WR
inputs are not effective. If the serial interface has been selected, the shift register and
counter are both reset.
However, the reset is always operated in any conditions of /CS1 and CS2.
