+/** A sample code for "mini board PCU9669/PCA9665"
+ *
+ *  @author  Akifumi (Tedd) OKANO, NXP Semiconductors
+ *  @version 1.0
+ *  @date    26-Mar-2012
+ *
+ *  Released under the MIT License: http://mbed.org/license/mit
+ *
+ *  An operation sample of PCU9669/PCA9665 I2C bus controller.
+ *  The mbed accesses the bus controller's parallel port (8/2 bit address and 8 bit data) by bit-banging.
+ *  The bit-banging is poerformed by PortInOut function of mbed library.
+ *
+ *    To make the code porting easier, all codes are partitioned into layers to abstract other parts.
+ *    The mbed specific parts are concentrated in lowest layer: "hardware_abs.*".
+ *    This module may need to be modified for the porting.
+ *
+ *    All other upper layers are writen in standard-C.
+ *
+ *    base code is written from 05-Sep-2011 to 09-Sep-2011.
+ *    And demo code has been build on 11-Sep-2011.
+ *    Debug and code adjustment has been done on 08-Sep-2011.
+ *    Small sanitization for main.cpp. All mbed related codes are moved in to "hardware_abs.*". 13-Oct-2011
+ *    hardware_abs are moved into parallel_bus library folder, 3 LED driver operation sample 13-Feb.-2012
+ *    PCU9669 and PCA9665 codes are packed in a project 14-Feb-2012.
+ *
+ *    Before builidng the code, please edit the file mini_board_PCU9669/config.h
+ *    Un-comment the target name what you want to target.
