DESCRIPTION
The R8A66153FP is a programmable I/O expander using a high-voltage CMOS process.
And has three sets of 8-bit I/O ports, two sets of 8-bit high voltage output ports, and one 4-bit input port.
FEATURES
● Output pattern can be written in input mode
● 8-bit X 2 high voltage output ports with IOL=24mA
www.DataSheet●4UC.cMomOS level schmitt trigger input
● Vcc=4.5~5.5V, Ta=-40~85oC
APPLICATION
● I/O port expansion for MCU.

CONTROL WORD
When (A0, A1, A2)=(1,1,1), data bus data is recognized as the control word.
This control word is to set the port condition and the bit set/reset function of port C. (see Fig.1 and Fig.2)
