Abstract
A microcontroller has a data memory divided into a plurality of memory banks, an address multiplexer for providing an address to the data memory, an instruction register providing a first partial address to a first input of the address multiplexer, a bank select register which is not mapped to the data memory for providing a second partial address to a the first input of the address multiplexer, and a plurality of special function registers mapped to the data memory, wherein the plurality of special function registers comprises an indirect access register coupled with a second input of the address multiplexer, and wherein the data memory comprises more than one memory bank of the plurality of memory banks that form a block of linear data memory to which no special function registers are mapped.
