is enabled or not. There are 16 channel-enable mode settings. The default
is to enable all channels.
A four-bit binary number represents the enable state of four channels, each
bit is a channel, the lowest bit is channel 0 and the highest bit is channel 3.

Mode 1: after communication breaks, output status is initial value
(output is 0, DA is the minimal value of present measurement range)
Mode 2: after communication breaks, output status is the status when
breaks.
