19. Multi-Function Timer Pulse Unit 3 (MTU3c)
(5) Cascaded Operation Example (d)
illustrates the operation when MTU1.TCNT and MTU2.TCNT have been cascaded and the TICCR.I2AE
bit has been set to 1 to include the MTIOC2A pin in the MTU1.TGRA input capture conditions. In this example, the
IOA[3:0] bits in MTU1.TIOR have selected occurrence of MTU0.TGRA compare match or input capture for the input
capture timing while the IOA[3:0] bits in MTU2.TIOR have selected the MTIOC2A rising edge for the input capture
timing.
Under these conditions, as MTU1.TIOR has selected occurrence of MTU0.TGRA compare match or input capture for
the input capture timing, the MTIOC2A edge is not used for MTU1.TGRA input capture condition although the I2AE bit
in TICCR has been set to 1.
