RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
23.2.21 Timer Subcounters (TCNTS)
Note: The TCNTS counters must not be accessed in 8-bit units; they should be accessed in 16-bit units.
The TCNTS counters are read-only counters that are used only in complementary PWM mode.
23.2.22 Timer Dead Time Data Registers (TDDR)
Note: The TDDR registers must not be accessed in 8-bit units; they should be accessed in 16-bit units.
The TDDR registers specify the MTU3.TCNT and MTU4.TCNT counter offset value in complementary PWM mode. In
complementary PWM mode, when the MTU3.TCNT and MTU4.TCNT counters are cleared and then restarted, the
TDDR register value is loaded into the MTU3.TCNT counter and the count operation starts.
