23. Multi-Function Timer Pulse Unit 2 (MTU2a)
(24) Operation When Error Occurs in Complementary PWM Mode and Operation is Restarted in
Complementary PWM Mode with New Settings
shows a case in which an error occurs in complementary PWM mode and operation is restarted in
complementary PWM mode after re-setting (operation is restarted using new cycle and duty settings).
Figure 23.139
Error Occurrence in Complementary PWM Mode, Recovery in Complementary PWM Mode
(1) to (10) are the same as in
(11) Set normal mode and make new settings (MTU output goes low).
(12) Disable output in MTU3 and MTU4 with the TOER register.
(13) Select the complementary PWM mode output level and enable or disable cyclic output with the TOCR register.
(14) Set complementary PWM mode.
(15) Enable output in MTU3 and MTU4 with the TOER register.
(16) Use the MPC and the port mode register (PMR) for the I/O port to set up MTU output.
(17) Restart operation by setting the TSTR register.
