Introduction to RS08
1.1
The RS08 platform is developed for extremely low cost applications. Its hardware size is optimized and
the overall system cost is reduced. The smaller hardware size allows the silicon to fit into a smaller
package, such as the 6-pin dual flat no lead package (DFN). The RS08 platform retains a similar
programming model as in the popular HC08/S08 platforms to allow easy source code migration between
the platforms.
The main features of the RS08 platform are:
1.1.1
The RS08 CPU registers include an 8-bit general purpose accumulator (A), 14-bit program counter (PC),
14-bit shadow program counter (SPC), and a 2-bit conditional code register (CCR). The CCR contains two
status flags and are tested for conditional branch instructions such as BCS and BEQ.
