19. Multi-Function Timer Pulse Unit 3 (MTU3c)
(b) When TGR is an Input Capture Register
shows an operation example in which TGRA has been designated as an input capture register, and buffer
operation has been designated for TGRA and TGRC.
Counter clearing by TGRA input capture has been set for TCNT, and both rising and falling edges have been selected as
the MTIOCnA pin input capture input edge. (n = 0 to 4)
As buffer operation has been set, when the TCNT value is transferred to TGRA upon occurrence of input capture A, the
value previously stored in TGRA is simultaneously transferred to TGRC.
