MTU Output Pin Initialization

8.8.1

Operating Modes

The MTU 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-synchronous PWM mode (channels 3 and 4)

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

8.8.2

Reset Start Operation

The MTU output pins (TIOC*) are initialized low by a reset or in standby mode. Since MTU pin

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

MTU pin states at that point are output to the ports. When MTU output is selected by the PFC

immediately after a reset, the MTU 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 MTU output pins is completed.

Note:

Channel number and port notation are substituted for *.
