This bit must be set to zero to enable operation of any timer or the rotary decoder. When set to one, it forces
a block-level reset and gates off the clocks to the block.
This bit must be set to zero for normal operation. When set to one, it gates off the clocks to the block.

Read-only view of the rotary decoder transition detecting state machine.
This bit field determines the divisor used to divide the 32-kHz on chip clock rate for oversampling (debouncing)
the rotary A and B inputs. Note that the divider value is actually the (value of this field+1).
