Note: If user decides to add own firmware using EVB90614 he must use program memory above 0x4000
(see PIC18F4550 datasheet). Also EEPROM memory addresses between 0x40 and 0x43 must be
maintained 0x00 or 0xFF otherwise the EVB90614 will not be recognized from the host when it is in
bootloader mode. For the latest information about this opportunity check www.melexis.com .
