24.3 Operation
The target pins for high-impedance control and conditions to place the pins in high-impedance are described below.
(1) MTU0 pin (MTIOC0A)
When any of the following conditions is satisfied, the pin is placed to the high-impedance state.
 POE8# input level detection
When the ICSR2.POE8F flag is set to 1 with POECR1.PE0ZE and ICSR2.POE8E set to 1.
 SPOER setting
When the SPOER.CH0HIZ bit is set to 1 with POECR1.PE0ZE set to 1.
 Detection of stopped oscillation
When the OSTSTF flag is set to 1 with POECR1.PE0ZE and ICSR3.OSTSTE set to 1.
 Event signal reception from the ELC
(2) MTU0 pin (MTIOC0B)
When any of the following conditions is satisfied, the pin is placed to the high-impedance state.
 POE8# input level detection
When the ICSR2.POE8F flag is set to 1 with POECR1.PE1ZE and ICSR2.POE8E set to 1.
 SPOER setting
When the SPOER.CH0HIZ bit is set to 1 with POECR1.PE1ZE set to 1.
 Detection of stopped oscillation
When the OSTSTF flag is set to 1 with POECR1.PE1ZE and ICSR3.OSTSTE set to 1.
 Event signal reception from the ELC
(3) MTU0 pin (MTIOC0C)
When any of the following conditions is satisfied, the pin is placed to the high-impedance state.
 POE8# input level detection
When the ICSR2.POE8F flag is set to 1 with POECR1.PE2ZE and ICSR2.POE8E set to 1.
 SPOER setting
When the SPOER.CH0HIZ bit is set to 1 with POECR1.PE2ZE set to 1.

 Event signal reception from the ELC
(4) MTU3 pins (MTIOC3B and MTIOC3D)
When any of the following conditions is satisfied, the pins are placed to the high-impedance state.
 POE0#, POE1#, and POE3# input level detection
When the ICSR1.POE3F, POE1F, or POE0F flag is set to 1 with POECR2.P1CZEA set to 1.
 MTIOC3B and MTIOC3D output level comparison
When the OCSR1.OSF1 flag is set to 1 with POECR2.P1CZEA and OCSR1.OCE1 set to 1.
 SPOER setting
When the SPOER.CH34HIZ bit is set to 1 with POECR2.P1CZEA set to 1.
 Detection of stopped oscillation
When the ICSR3.OSTSTF flag is set to 1 with POECR2.P1CZEA and ICSR3.OSTSTE set to 1.
