RX23W Group 25. 16-Bit Timer Pulse Unit (TPUa)
x: Don’t care
Note 1. When the BFA bit in TPU3.TMDR is set to 1 (TPU3.TGRA and TPU3.TGRC are used for buffer operation) and TPU3.TGRC is
used as a buffer register, this setting is invalid and input capture/output compare is not generated.
Note 2. When the BFB bit in TPU3.TMDR is set to 1 (TPU3.TGRB and TPU3.TGRD are used for buffer operation) and TPU3.TGRD is
used as a buffer register, this setting is invalid and input capture/output compare is not generated.
Note 3. When the TPSC[2:0] bits in TPU4.TCR are set to 000b and PCLK/1 is used as the TPU3.TCNT count clock, this setting is invalid
and input capture is not generated.
Note 4. Selected by the ICSELD bit in TPU3.TMDR.
