TAAnCCR0 and TAAnCCR1 register rewrite is possible for timer AA during
timer operation (TAAnCE = 1), but the write method (any time write, reload)
differs depending on the mode.

When data is written to the TAAnCCRm register during timer operation, it is
transferred at any time to CCRm buffer register and used as the 16-bit counter
comparison value.
