Notes:  1.  When bits TPSC2 to TPSC0 in TCR_4 are set to B'000 and φ/1 is used as the TCNT_4 
count clock, this setting is invalid and input capture is not generated. 
  2.  When the BFB bit in TMDR_3 is set to 1 and TGRD_3 is used as a buffer register, this 
setting is invalid and input capture/output compare is not generated.
