While the duty is "1:N" (BRTM_S_MD.BRTM_Sn_MD = 1), the cycle and operation of BRTMn are shown in
the figure below.
BRTM_SnCLK Cycle = (N + 1) × Count Clock Cycle
(N: Setting value of BRTM_Sn_OC, The setting of N = 0x00 is disabled.)

When the duty is "1:N", the value of "0x00" must not be set to BRTM_Sn_OC.
.. ..
In Clock-Synchronous communication, BRTM_SCnCLK with "1:N" duty must not be used as
a transfer clock when SCnMD1.SCnCKM is "0".
