Section 18 Multi-Function Timer Pulse Unit (MTU)
18.8 MTU Output Pin Initialization
18.8.1 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.
18.8.2 Reset Start Operation
The MTU output pins (TIOC*) are initialized to low by a power-on 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 power-on 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 *.
