When TAAnCCS1 = 1 and TAAnCCS0 = 0
When TAAnCE = 1 is set, the counter counts from 0000H to FFFFH and free-
running count-up operation continues until TAAnCE = 0 is set. The TAAnCCR0
register is used as a compare register. An interrupt signal is output upon a
match between the value of the 16-bit counter and the setting value transferred
to the CCR0 buffer register from the TAAnCCR0 register as an interval
function. Even if TAAnOE1 = 1 to realize the output function, TAAnCCR1
register cannot control TOAAn1 because it is used as capture register.
