Note The 16-bit counter is not cleared upon a match between the 16-bit counter value and the CCR1
buffer register value. It is cleared upon a match between the 16-bit counter value and the CCR0
buffer register value.
Caution Writing to the TAA0CCR1 register includes enabling of batch write. Thus, rewrite the
TAA0CCR1 register after rewriting the TAA0CCR0 register.
