Where:
C1: 
Byte 3 is present when the memoryAddress parameter contains 3 or 4 bytes.
C2: 
Byte 4 is present when the memoryAddress parameter contains 4 bytes.
C3: 
The size of the dataRecord parameter shall be at least one byte if the sub-function value is of type
download and may be 0 bytes if the sub-function value is of type downloadAndExecuteOrExecute
Note 1: 
Byte1 in the memoryAddress parameter is always the most significant byte of the address and the last byte of the memoryAddress
parameter (Byte2 for 2-byte addressing, Byte3 for 3-byte addressing, or Byte4 for 4-byte addressing) is always the least significant byte of
the memoryAddress parameter.

downloadAndExecuteOrExecute
This sub-parameter level of operation is used to command a node to receive a block
transfer, download the data received to the memory address specified in the
startingAddress[] parameter, and execute the data (program) downloaded. This sub-
parameter command can also be used to execute a previously downloaded program by
sending the request message with no data in the dataRecord[ ].
