24. Port Output Enable 2 (POE2a)
24.2.6
Port Output Enable Control Register 2 (POECR2)
Note 1. Can be modified only once after a reset.
When this function is not used, write 00h to this register.
P3CZEA Bit (MTU Port 3 High-Impedance Enable)
This bit gives permission regarding whether or not the MTIOC4B and MTIOC4D pins for complementary PWM output
from the MTU are placed in the high-impedance. It also gives permission regarding whether or not the levels on the
MTIOC4B and MTIOC4D pins are compared.
P2CZEA Bit (MTU Port 2 High-Impedance Enable)
This bit gives permission regarding whether or not the MTIOC4A and MTIOC4C pins for complementary PWM output
from the MTU are placed in the high-impedance. It also gives permission regarding whether or not the levels on the
MTIOC4A and MTIOC4C pins are compared.
P1CZEA Bit (MTU Port 1 High-Impedance Enable)
This bit gives permission regarding whether or not the MTIOC3B and MTIOC3D pins for complementary PWM output
from the MTU are placed in the high-impedance. It also gives permission regarding whether or not the levels on the
MTIOC3B and MTIOC3D pins are compared.
