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.
