20. Port Output Enable 3 (POE3C)
20.2.8
Port Output Enable Control Register 1 (POECR1)
Note 1. Can be modified only once after a reset.
The POECR1 register controls high-impedance state of the MTU0 pins.
MTU0AZE Bit (MTIOC0A (PB3) Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC0A output of PB3 to the high-impedance state when any of the
ICSR3.POE8F flag, SPOER.MTUCH0HIZ bit, and ICSR6.OSTSTF flag (when the OSTSTE bit is 1), or, as additionally
specified in the POECR5 register, the ICSRn.POEmF flag (n = 1, 4; m = 0, 10), or POECMPFR.CnFLAG flag (n = 0 to
2), is set to 1.
MTU0BZE Bit (MTIOC0B (PB2) Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC0B output of PB2 to the high-impedance state when any of the
ICSR3.POE8F flag, SPOER.MTUCH0HIZ bit, and ICSR6.OSTSTF flag (when the OSTSTE bit is 1), or, as additionally
specified in the POECR5 register, the ICSRn.POEmF flag (n = 1, 4; m = 0, 10), or POECMPFR.CnFLAG flag (n = 0 to
2), is set to 1.
MTU0CZE Bit (MTIOC0C (PB1) Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC0C output of PB1 to the high-impedance state when any of the
ICSR3.POE8F flag, SPOER.MTUCH0HIZ bit, and ICSR6.OSTSTF flag (when the OSTSTE bit is 1), or, as additionally
specified in the POECR5 register, the ICSRn.POEmF flag (n = 1, 4; m = 0, 10), or POECMPFR.CnFLAG flag (n = 0 to
2), is set to 1.
MTU0DZE Bit (MTIOC0D (PB0) Pin High-Impedance Enable)
This bit specifies whether to switch the MTIOC0D output of PB0 to the high-impedance state when any of the
ICSR3.POE8F flag, SPOER.MTUCH0HIZ bit, and ICSR6.OSTSTF flag (when the OSTSTE bit is 1), or, as additionally
