Description
MTIOC3B and MTIOC3D
Output
Pin combinations for output-level comparison and high-impedance control can be selected
by POE registers.
The pins for MTU complementary PWM output are placed in high-impedance when the pins
simultaneously output an active level for one or more PCLK clock cycles.
(When the MTU.TOCR1.TOCS bit = 0:
The active level is low level if the MTU.TOCR1.OLSP and OLSN bits are 0, and the active
level is high level if the MTU.TOCR1.OLSP and OLSN bits are 1.
When the MTU.TOCR1.TOCS bit = 1:
The active level is low level if the MTU.TOCR2.OLS3N, OLS3P, OLS2N, OLS2P, OLS1N,
and OLS1P bits are 0, and the active level is high level if the MTU.TOCR2.OLS3N, OLS3P,
OLS2N, OLS2P, OLS1N, and OLS1P bits are 1.)
