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 0000H or 00H, the 8/16-bit capture timer/counter cannot generate an interrupt. Therefore, when using interrupts, set a value greater than or equal to 0001H or 01H. The 8/ 16-bit capture timer/counter also cannot generate an interrupt if the counter function detects the 0000H or 00H width.
