M2
input
The combination of
M2M1M0 determines the
module's 8 operating modes,
which
require a 1K protection resistor
in series
17
GND
Referential
Module ground
18
M0
input
The combination of
M2M1M0 determines the
module's 8 operating modes,
which
require a
1K protection resistor in series when used
And add a pull-up resistor of 1M (not floating, if not groundable).
19
M1
input
The combination of M2M1M0 determines that
a
1K
protection resistor
