— Wait the end of the command:
command echo = 0040(h)
command error code ≠ FFFF(h) (end of command)
— Deactivate the “Write parameters” command:
Write at the address 00(h) the value 0000(h)
Byte 0 = 00(h) (Bit 6 = 0)
Byte 1 = 00(h)
The master instrument must always set to zero the command bit. If it is not done, the slave instrument
will not detect the following command on this bit. It has detection on the rising edge (when the bit
state goes from 0 to 1).
