7.2.12
BETR is a 16-bit readable/writable register. When the execution-times break condition of channel
B is enabled, this register specifies the number of execution times to make the break. The
maximum number is 2
break interrupt is requested when the break condition is satisfied after BETR becomes H'0001.
