[1] Set the TMDR3.LWA bit of MTU1 to 0.
Set the TMDR1.MD[3:0] bits to select the
phase counting mode.
[2] When the MTU2 is set to phase counting
mode, select the A- or B-phase input
signal with the PHCKSEL bit in TMDR3.
This setting is not necessary for MTU1
because MTCLKA and MTCLKB are
always selected for A-phase and B-
phase, respectively.

the count operation.
