... Memory Programming Specification This document includes the programming specifications for the following devices: • PIC10F220 • 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 ...

... The programming sequence loads a word, programs, verifies and finally increments the PC. Program/Verify mode entry will set the address to 0x1FF for the PIC10F220 and 0x3FF for the PIC10F222. The Increment Address command will increment the PC. The available commands are shown in Table 3-1. FIGURE 3-1: ...

... 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.

... 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. Checksum computation for the PIC10F220/222 is shown in Table 5-2 ...

... For example, ID0 = 0x1, ID1 = 0x2, ID2 = 0x3, ID3 = 0x4, then SUM_ID = 0x1234. *Checksum = [Sum of all the individual expressions] MODULO [0xFFFF Addition & = Bitwise AND Note 1: Checksum shown assumes that SUM_ID contains the unprotected checksum.
