... Legend Input Output Power Note 1: In the PIC12F510, the programming high voltage is internally generated. To activate the Program/Verify mode, high voltage of I IHH © 2007 Microchip Technology Inc. PIC12F510 1.1 Hardware Requirements The PIC12F510 requires one power supply for V (5.0V) and one for V 1 ...

... MEMORY MAPPING 2.1 User Program Memory Map The user memory space extends from (0x000-0x3FF) on the PIC12F510. In Program/Verify mode, the pro- gram memory space extends from (0x000-0x7FF) for the PIC12F510. The first half, (0x000-0x3FF), is user program memory. The second half, (0x400-0x7FF), is configuration memory. The PC will increment from (0x000-0x3FF) then to 0x400, (not to 0x000) ...

... Data is transferred LSb first. During Read commands, in which the data is output from the PIC12F510, 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) ...

... PIC12F510 3.1.2.1 Load Data For Program Memory After receiving this command, the chip will load in a 14-bit “data word” when 16 cycles are applied, as described previously. Because this is a 12-bit core, the two MSbs of the data word are ignored. A timing diagram for the Load Data command is shown in Figure 3-1 ...

... PIC12F510 3.1.2.5 End Programming The End Programming command terminates the program process. A delay of T (see Table 6-1) is DIS required before the next command to allow the internal programming voltage to discharge (see Figure 3-6).
