• Manufacturer Part Number: saa-xc866
• Description: 8-bit Single-chip Microcontroller
• Manufacturer: Infineon Technologies Corporation

Note: The RMAP bit must be cleared/set by ANL or ORL instructions. The rest bits of
As long as bit RMAP is set, the mapped SFR area can be accessed. This bit is not
