8-Bit Single-Chip Microcontroller

Infineon Technologies 

XC864

Functional Description

Note: The RMAP bit must be cleared/set by ANL or ORL instructions.

As long as bit RMAP is set, the mapped SFR area can be accessed. This bit is not

cleared automatically by hardware. Thus, before standard/mapped registers are

accessed, bit RMAP must be cleared/set, respectively, by software.
