... PIC10F222 1.0 PROGRAMMING THE PIC10F220/222 The PIC10F220/222 is programmed using a serial method. The Serial mode will allow the PIC10F220/222 to be programmed while in the user’s system. This allows for increased design flexibility. This programming specification applies to PIC10F220/222 devices in all packages. Pin Diagrams ...

... 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 0x1FF for the PIC10F220 or 0x3FF for the PIC10F222 to 0x000.

... PIC10F220/222 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 3-7).

... Checksum Computation 5.3.1 CHECKSUM Checksum is calculated by reading the contents of the PIC10F220/222 memory locations and adding up the opcodes up to the maximum user addressable location (e.g., 0x1FF for the PIC10F222). Any Carry bits exceeding 16 bits are neglected. Finally, the Configuration Word (appropriately masked) is added to the checksum ...
