... Legend Input Output Power Note 1: In the PIC16F506, the programming high voltage is internally generated. To activate the Program/Verify mode, V (see Table 6-1) needs to be applied to the MCLR input.

... MEMORY MAPPING 2.1 User Program Memory Map The user memory space extends from (0x000-0x3FF) on the PIC16F506. In Program/Verify mode, the program memory space extends from (0x000-0x7FF). The first half, (0x000-0x3FF), is user program memory. The second half, (0x400-0x7FF), is configuration memory. The PC will increment from (0x000 to 0x3FF), then to 0x400 (not to 0x000) ...

... Data is transferred LSb first. During Read commands, in which the data is output from the PIC16F506, the ICSPDAT pin transitions from the high-impedance input state to the low-impedance output state at the rising edge of the second data clock (first clock edge after the Start cycle). The ICSPDAT pin returns to the high-impedance state at the rising edge of the 16th data clock (first edge of the Stop cycle) ...

... PIC16F506 3.1.2.3 Increment Address The PC is incremented when this command is received. A timing diagram of this command is shown in Figure 3- not possible to decrement the address counter. To reset this counter, the user must either exit and re-enter Program/Verify mode or increment the PC from 0x7FF to 0x000. FIGURE 3-4: ...
