MTU2 Output Pin Initialization

12.8.1

Operating Modes

The MTU2 has the following six operating modes. Waveform output is possible in all of these

modes.

• Normal mode (channels 0 to 4)

• PWM mode 1 (channels 0 to 4)

• PWM mode 2 (channels 0 to 2)

• Phase counting modes 1 to 4 (channels 1 and 2)

• Complementary PWM mode (channels 3 and 4)

• Reset-synchronized PWM mode (channels 3 and 4)

The MTU2 output pin initialization method for each of these modes is described in this section.

12.8.2

Reset Start Operation

The MTU2 output pins (TIOC*) are initialized low by a power-on reset. Since MTU2 pin function

selection is performed by the pin function controller (PFC), when the PFC is set, the MTU2 pin

states at that point are output to the ports. When MTU2 output is selected by the PFC immediately

after a power-on reset, the MTU2 output initial level, low, is output directly at the port. When the

active level is low, the system will operate at this point, and therefore the PFC setting should be

made after initialization of the MTU2 output pins is completed.

Note:

Channel number and port notation are substituted for *.
