16.16 Precautions when Using 8/16-bit Composite Timer

This section explains the precautions to be taken when using the 8/16-bit composite
timer.
Precautions when Using 8/16-bit Composite Timer
When changing the timer function by using the timer operation mode select bits (T00CR0/T01CR0:F3, F2,
F1, F0), the timer operation must be stopped (T00CR1/T01CR1:STA = 0) before clearing the interrupt flag
(T00CR1/T01CR1:IF, IR), interrupt enable bits (T00CR1/T01CR1:IE, T00CR0/T01CR0:IFE) and buffer
full flag (T00CR1/T01CR1:BF).
When the PWC or input capture function has been selected, an interrupt may occur even before the timer is
activated (STA = 0). Therefore, nullify the value of the 8/16-bit composite timer 00/01 data register
(T00DR/T01DR) obtained before the activation.
