R8A66153FP

Port E and Port F

Port E and Port F are 8-bit high voltage output ports with Vo=24V/IOL=24mA. Output transistor is N-ch

open drain transistor.

When this port is selected, data bus data is written into the port latch by the positive edge of WR.

And if is set to output enable, port latch

Port G

Port G is a input port with CMOS schmitt trigger. When this port is selected and RD="L", input data is

appears to the data bus.
