These bits are always read as 0. The write value
should always be 0.
MTU2S Output High-Impedance
This bit specifies whether to place the large current
pins for the MTU2S in the high-impedance state.
0: Does not place the pins in the high-impedance
[Clearing conditions]
•
•
1: Places the pins in the high-impedance state
[Setting condition]
