ATmega1284P
• Bit 2 – OCF3B: Timer/Counter3, Output Compare B Match Flag
This flag is set in the timer clock cycle after the counter (TCNT3) value matches the Output
Compare Register B (OCR3B).
Note that a Forced Output Compare (FOC3B) strobe will not set the OCF3B Flag.
OCF3B is automatically cleared when the Output Compare Match B Interrupt Vector is exe-
cuted. Alternatively, OCF3B can be cleared by writing a logic one to its bit location.
• Bit 1 – OCF3A: Timer/Counter3, Output Compare A Match Flag
This flag is set in the timer clock cycle after the counter (TCNT3) value matches the Output
Compare Register A (OCR3A).
Note that a Forced Output Compare (FOC3A) strobe will not set the OCF3A Flag.
OCF3A is automatically cleared when the Output Compare Match A Interrupt Vector is exe-
cuted. Alternatively, OCF3A can be cleared by writing a logic one to its bit location.
• Bit 0 – TOV3: Timer/Counter1, Overflow Flag
The setting of this flag is dependent of the WGMn3:0 bits setting. In Normal and CTC modes,
the TOV3 Flag is set when the timer overflows. Refer to
Table 14-5 on page 133
for the TOV3
Flag behavior when using another WGMn3:0 bit setting.
TOV3 is automatically cleared when the Timer/Counter3 Overflow Interrupt Vector is executed.
Alternatively, TOV3 can be cleared by writing a logic one to its bit location.
