CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER
When the counter operation stops according to the timer start bits (TCR0: TSTR0 = 0 and TCR1: TSTR1 =
0) and the interrupt source occurs at the same time, the interrupt request flag bits (TCR0: TIF0 and TCR1:
TIF1) are not set.
In the capture mode, no external clock can be selected; set the count clock bits (TCS12,TCS11, and TCR1:
TCS10) to a value other than 111
B
.
● Note on using interrupts
If the compare register value is 0000
H
or 00
H
, the 8/16-bit capture timer/counter cannot generate interrupts.
For this reason, when using interrupts, set a value greater than or equal to 0001
H
or 01
H
. The 8/16-bit
capture timer/counter cannot generate interrupts if the capture counter function detects the 0000
H
or 00
H
width.
