1. The example code assumes that the part specific header file is included. For I/O Registers
located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI" instructions must
be replaced with instructions that allow access to extended I/O. Typically "LDS" and "STS"
combined with "SBRS", "SBRC", "SBR", and "CBR".
