Write Registers Command (0x10)
This command writes values to multiple registers in sequential order. It is used for automatic program download
only to transmit program data one step at a time to the MC. See the Automatic Program Parameters section
for the list of registers and their use. If this command is used to write to registers other than the correct program
step registers, the MC will respond with an acknowledgment that the message was received; however, the
command will not be executed.
Packet sent to the MC:
controller address (1 byte)
write command (0x10)
starting register high byte
starting register low byte
number of registers to write high byte
number of registers to write low byte
number of data bytes
data high byte
data low byte
…
…
register n data high byte
register n data low byte
CRC low byte
CRC high byte
Packet returned from the MC:
controller address (1 byte)
write command (0x10)
starting register high byte
starting register low byte
number of registers to write high byte
