MEMORY ORGANIZATION The PIC10F220/222 memories are organized into pro- gram memory and data memory. Data memory banks are accessed using the File Select Register (FSR). 4.1 Program Memory Organization for the PIC10F220 The PIC10F220 devices have a 9-bit Program ...
Page 16
PIC10F220/222 4.3 Data Memory Organization Data memory is composed of registers or bytes of RAM. Therefore, data memory for a device is specified by its register file. The register file is divided into two functional groups: Special Function Registers (SFR) ...

PIC10F220/222 4.9 Indirect Data Addressing; INDF and FSR Registers The INDF register is not a physical register. Addressing INDF actually addresses the register whose address is contained in the FSR register (FSR is a pointer). This is indirect addressing. 4.9.1 ...
Page 23
I/O PORT As with any other register, the I/O register(s) can be written and read under program control. However, read instructions (e.g., MOVF GPIO, W) always read the I/O pins independent of the pin’s Input/Output modes. On Reset, all ...
