TIMER B  
[Precautions for event counter mode]  
[Precautions for event counter mode]  
While counting is in progress, by reading the timer Bi register, the counter value can be read out at  
arbitrary timing. However, if the timer Bi register is read at the reload timing shown in Figure 8.4.5, a value  
FFFF16is read out. If reading is performed in the period from when a value is set into the timer Bi register  
with the counter stopped until the counter starts counting, the set value is correctly read out.
