AT43USB326
3313D–USB–04/06
Timer/Counter Interrupt Mask Register – TIMSK
Bit 7:2 – Res: Reserved Bits
These bits are reserved bits in the AT43USB326 and always read zero.
Bit 1 – TOIE0: Timer/Counter0 Overflow Interrupt Enable
When the TOIE0 bit is set (one) and the I-bit in the Status Register is set (one), the
Timer/Counter0 Overflow interrupt is enabled. The corresponding interrupt (at vector $007) is
executed if an overflow in Timer/Counter0 occurs, i.e., when the TOV0 bit is set in the TIFR.
Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB326 and always reads zero.
Timer/Counter Interrupt Flag Register – TIFR
Bit 7:2 – Res: Reserved Bits
These bits are reserved bits in the AT43USB326 and always read zero.
Bit 1 – TOV: Timer/Counter0 Overflow Flag
The bit TOV0 is set (one) when an overflow occurs in Timer/Counter0. TOV0 is cleared by the
hardware when executing the corresponding interrupt handling vector. Alternatively, TOV0 is
cleared by writing a logic one to the flag. When the SREG I- bit, and TOIE0 (Timer/Counter0
Overflow Interrupt Enable), and TOV0 are set (one), the Timer/Counter0 Overflow interrupt is
executed.
Bit 0 – Res: Reserved Bit
This bit is a reserved bit in the AT43USB326 and always reads zero.
