DS41302D-page 11 PIC12F609/615/617/12HV609/615 2.0 MEMORY ORGANIZATION 2.1 Program Memory Organization The PIC12F609/615/617/12HV609/615 has a 13-bit program counter capable of addressing an 8K x 14 program memory space. Only the first 1K x 14 (0000h- 03FFh) for the PIC12F609/615/12HV609/615 is physically implemented. For the PIC12F617, the first 2K x 14 (0000h-07FFh) is physically implemented. Accessing a location above these boundaries will cause a wrap-around within the first 1K x 14 space for PIC12F609/615/12HV609/615 devices, and within the first 2K x 14 space for the PIC12F617 device. The Reset vector is at 0000h and the interrupt vector is at 0004h (see Figure 2-1). FIGURE 2-1: PROGRAM MEMORY MAP AND STACK FOR THE PIC12F609/615/12HV609/615 FIGURE 2-2: PROGRAM MEMORY MAP AND STACK FOR THE PIC12F617 2.2 Data Memory Organization The data memory (see Figure 2-3) is partitioned into two banks, which contain the General Purpose Registers (GPR) and the Special Function Registers (SFR). The Special Function Registers are located in the first 32 locations of each bank. Register locations 40h-7Fh in Bank 0 are General Purpose Registers, implemented as static RAM. For the PIC12F617, the register locations 20h-7Fh in Bank 0 and A0h-EFh in Bank 1 are general purpose registers implemented as Static RAM. Register locations F0h-FFh in Bank 1 point to addresses 70h-7Fh in Bank 0. All other RAM is unimplemented and returns ‘0’ when read. The RP0 bit of the STATUS register is the bank select bit. RP0 0 Bank 0 is selected 1 Bank 1 is selected PC<12:0> 13 0000h 0004h 0005h 03FFh 0400h 1FFFh Stack Level 1 Stack Level 8 Reset Vector Interrupt Vector On-chip Program Memory CALL, RETURN RETFIE, RETLW Stack Level 2 Wraps to 0000h-03FFh Note: The IRP and RP1 bits of the STATUS register are reserved and should always be maintained as ‘0’s.
