Given the following example MCU data or program block (must be a multiple of 4 bytes for these blocks):
0x10 0x20 0x30 0x40 0x50 0x60 0x70 0x80
The checksum = 0x10 + 0x20 + 0x30 + 0x30 + 0x40 + 0x50 + 0x60 + 0x70 + 0x80 = 0x240, so
the values put in the checksum fields are MS byte = 0x02 and LS byte = 0x40.
If the checksum is >FFFFh, then the 2-byte checksum field is the least-significant 2 bytes.
For example, if the checksum is 0x1D 45B6, the checksum field is MS byte = 0x45 and LS byte = 0xB6.
