 * DESCRIPTION
 *
 *   EEPROM reading and writing test program. To use test this program connect
 *   a nRF24E1 or nRF9E5 evaluation board to the serial port of your computer
 *   and start up a terminal emulator in 19200 baud. Hit 'r' in the terminal
 *   window to read a byte from the EEPROM and 'w' to write a byte. Please also
 *   read the description in the header of "eeprom.c".
 *
 *   NOTE: This source code is compatible with both nRF9E5 and nRF24E1. Please
 *         select the device you are using by uncommenting/commenting the
 *         appropriate line at the top of "nrfexx.h".
 *
 * COMPILER:
 *
 *   This program has been tested with Keil C51 V7.09
