UP RESISTORS OF THE REFERENCE SWITCH INPUTS
SIO can be used to switch the pull-up resistors for all reference switch inputs on and off. Bank 0 is used
for this purpose.

Description
3 REF_L
Input for reference / limit switch left
4 REF_R
Input for reference / limit switch right
Using the bitmask of this SIO command, the pull-up resistors can be switched on/off in two functional
groups: bit 0 is used for motor 0, 1, and 2. Bit 1 is used for motor 3, 4, and 5. Setting the bit will switch
on the pull-ups, clearing it will switch them off.
