MTU2 Channel 3 and 4 Output High-Impedance
This bit specifies whether to place the large current
pins for the MTU2 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]
•
Reserved
These bits are always read as 0. The write value
should always be 0.
MTU2 PE3 High-Impedance Enable
This bit specifies whether to place the PE3/TIOC0D
pin for channel 0 in the MTU2 in the high-impedance
state when either POE8F or MTU2CH0HIZ bit is set
to 1.
0: Does not place the pin in the high-impedance state
1: Places the pin in the high-impedance state
