CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER
Notes:
• When the counter value matches the TDR0 value and at the same time the counter stops (TCR0:
TSTR0 = 0), the TIF0 bit is not set.
If the T0IEN bit is set to "1" (enable) when the TIF0 bit is "1", an interrupt request is generated
immediately.
• If the compare register value is 0000
H
or 00
H
, the 8/16-bit capture timer/counter cannot generate an
interrupt. Therefore, when using interrupts, set a value greater than or equal to 0001
H
or 01
H
. The 8/
16-bit capture timer/counter also cannot generate an interrupt if the counter function detects the
0000
H
or 00
H
width.
