20. Port Output Enable 3 (POE3C)
20.2.9
Port Output Enable Control Register 2 (POECR2)
Note 1. Can be modified only once after a reset.
The POECR2 register controls high-impedance state of the MTU complementary PWM output pins (MTU3 and MTU4
pins).
MTU4BDZE Bit (MTIOC4B/MTIOC4D Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC4B output and MTIOC4D output to the high-impedance state when at
least one of the OCSR1.OSF1 flag, ICSR1.POE0F flag, SPOER.MTUCH34HIZ bit, ICSR6.OSTSTF flag (when the
OSTSTE bit is 1), or, as additionally specified in the POECR4 register, the ICSRn.POEmF flag (n = 3, 4; m = 8, 10), or
POECMPFR.CnFLAG flag (n = 0 to 2) is set to 1.
MTU4ACZE Bit (MTIOC4A/MTIOC4C Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC4A output and MTIOC4C output to the high-impedance state when at
least one of the OCSR1.OSF1 flag, ICSR1.POE0F flag, SPOER.MTUCH34HIZ bit, ICSR6.OSTSTF flag (when the
OSTSTE bit is 1), or, as additionally specified in the POECR4 register, the ICSRn.POEmF flag (n = 3, 4; m = 8, 10), or
POECMPFR.CnFLAG flag (n = 0 to 2) is set to 1.
MTU3BDZE Bit (MTIOC3B/MTIOC3D Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC3B output and MTIOC3D output to the high-impedance state when at
least one of the OCSR1.OSF1 flag, ICSR1.POE0F flag, SPOER.MTUCH34HIZ bit, ICSR6.OSTSTF flag (when the
OSTSTE bit is 1), or, as additionally specified in the POECR4 register, the ICSRn.POEmF flag (n = 3, 4; m = 8, 10), or
POECMPFR.CnFLAG flag (n = 0 to 2) is set to 1.
