23. Multi-Function Timer Pulse Unit 2 (MTU2a)
x: Don't care
Note 1. When the MTU0.TMDR.BFA bit is set to 1 and the MTU0.TGRC register is used as a buffer register, this setting is invalid and
input capture/output compare is not generated.
Note 2. When PCLK/1 is selected as the count clock for MTU1, MTU0 input capture is not generated. Do not select PCLK/1 as the count
clock for MTU1.
