20. Port Output Enable 3 (POE3C)
20.2.7
Software Port Output Enable Register (SPOER)
The SPOER register is used to put the outputs of the corresponding pins in the high-impedance state.
MTUCH34HIZ Bit (MTU3 and MTU4 Pin High-Impedance Enable)
This bit specifies whether to put the outputs of the MTU complementary PWM output pins (MTIOC3B, MTIOC3D,
MTIOC4A, MTIOC4B, MTIOC4C, and MTIOC4D) in the high-impedance state.
[Setting condition]
By writing 1 to the MTUCH34HIZ bit
[Clearing conditions]
Reset
By writing 0 to the MTUCH34HIZ bit after reading MTUCH34HIZ = 1
MTUCH0HIZ Bit (MTU0 Pin High-Impedance Enable)
This bit specifies whether to put the outputs of the MTU0 pins in the high-impedance state.
[Setting condition]
By writing 1 to the MTUCH0HIZ bit
[Clearing conditions]
Reset
By writing 0 to the MTUCH0HIZ bit after reading MTUCH0HIZ = 1
