The state
'10', on bits 3:2 and 7:6, is not prevented by HW but shall never be set by SW. State '10' means that the interface is powered
with the pull-downs active, this state correspond to state
'00' with the regulator being switched on. Setting the state to '10' does not have
any impact on the corresponding regulator bit setting. The regulator control bits do not impact the state bits in this register. The regulator
control bits however do impact the status bits in the status register.

means that the counter is not used, i.e. no
debounce.

Reset value: 04h

Updating the register causes the counter to restart with the new value if the counter is counting when the register is updated. The new
value shall take affect no later than one clock cycle (32 KHz) after the register has been updated.
