(Note 2, 3)
Note 1: Read and write data in 16-bit units.
Note 2: When the timer Ai register is set to "000016", the counter does not operate
and a timer Ai interrupt does not occur.
Note 3: Use MOV instruction to write to this register.
Note 4: Do not write to these registers synchronously with a timer B2 underflow.
