24.2.4 Software Port Output Enable Register (SPOER)
CH34HIZ Bit (MTU3 and MTU4 Output High-Impedance Enable)
This bit selects whether to place the MTU complementary PWM output pins (MTIOC3B, MTIOC3D, MTIOC4A,
MTIOC4B, MTIOC4C, MTIOC4D) in high-impedance.
[Setting conditions]
 By writing 1 to CH34HIZ
 An event signal from the event link controller (ELC) is received.
[Clearing condition]
 By writing 0 to CH34HIZ after reading CH34HIZ = 1
CH0HIZ Bit (MTU0 Output High-Impedance Enable)
This bit selects whether to place the MTU0 pins (MTIOC0A, MTIOC0B, MTIOC0C) in high-impedance.
[Setting conditions]
 By writing 1 to CH0HIZ
 An event signal from the event link controller (ELC) is received.
[Clearing condition]
 By writing 0 to CH0HIZ after reading CH0HIZ = 1
