17.2
17.2.9 Group write register
Using this command it is possible to write a register in several MIS/SMCs with one com-
mand.
The command includes a sequence number which must be changed for each write. This
is used so that the same command can be written several times, to ensure that all con-
trollers received it. The last received sequence id can be read in register 148.
Controller sends
<GWrite><Group><Sequence><RegNum><Len><Data><End>

Clear out- Modifies the outputs. The bits set in the "Set outputs" data will be set and cleared
puts (8bit) for "Clear outputs".
Example:
The data 0x06,0x01 sets output 2+3 and clears output 1
Reserved
Prepare the flash for a new program. Data 1 specifies the size of the program in
bytes.
