... Memory Programming Specification This document includes the programming specifications for the following devices: • PIC12F508 • PIC12F509 1.0 PROGRAMMING THE PIC12F508/509 The PIC12F508/509 is programmed using a serial method. The Serial mode will allow the PIC12F508/509 to be programmed while in the user’s system. This ...

... The PC will increment from (0x000-0x1FF) and (0x000-0x3FF), respectively, then to 0x200 and 0x400, respectively (not to 0x000). In the configuration memory space, 0x200-0x23F for the PIC12F508 and 0x400-0x43F for the PIC12F509 are physically implemented. However, only locations 0x200-0x203 and 0x400-0x403 are available. Other locations are reserved. ...

... The programming sequence loads a word, programs, verifies and finally increments the PC. Program/Verify mode entry will set the address to 0x3FF for the PIC12F508 and 0x7FF for the PIC12F509. The Increment Address command will increment the PC. The available commands are shown in Table 3-1. FIGURE 3-1: ...
