9.8 MTU2 Output Pin Initialization
9.8.1 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.
9.8.2 Reset Start Operation
The MTU2 output pins (TIOC*) are initialized low by a reset and in standby mode. 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 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 *.
