19. Multi-Function Timer Pulse Unit 3 (MTU3c)
x: Don't care
Note 1. When the MTU0.TMDR1.BFB bit is set to 1 and MTU0.TGRD register is used as a buffer register, this setting is invalid and input
capture/output compare is not generated.
Note 2. When PCLKB/1 is selected as the count clock for MTU1, MTU0 input capture is not generated. Do not select PCLKB/1 as the
count clock for MTU1.
