Smart Card Reader Flash MCU
IAP Flash Program Memory Registers
There are two address registers, four 16-bit data registers and two control registers. The address
and data high byte registers together with the control registers are located in Sector 1 while other
registers are located in Sector 0. Read and Write operations to the Flash memory are carried out
using 16-bit data operations using the address and data registers and the control register. Several
registers control the overall operation of the internal Flash Program Memory. The address registers
are named FARL and FARH, the data registers are named FDnL and FDnH and the control registers
are named FCR and FRCR. As the FARL and FDnL registers are located in Sector 0, they can
be directly accessed in the same way as any other Special Function Register. The FARH, FDnH,
FCR and FRCR registers, being located in Sector 1, can be addressed directly only using the
corresponding extended instructions or can be read from or written to indirectly using the MP1H/
MP1L or MP2H/MP2L Memory Pointer pairs and Indirect Addressing Register, IAR1 or IAR2.
