Assert Acknowledge flag.
When this bit is set, an acknowledge is returned
after any one of the following conditions:
Own slave address is received
General call address is received (S1ADR.GC = 1)
A data byte is received, while the device is programmed to be a master receiver
A data byte is received, while the device is selected slave receiver.
When the bit is reset, no acknowledge is returned. Consequently, no interrupt is
requested when the own address or general call address is received.

Timer 1 overflow flag.
Set by hardware on Timer/counter overflow. Cleared by
hardware when processor vectors to interrupt routine.
Timer 1 run control bit.
Set/cleared by software to turn Timer/counter on/off.
Timer 0 overflow flag.
Set by hardware on Timer/counter overflow. Cleared by
hardware when processor vectors to interrupt routine.
Timer 0 run control bit.
Set/cleared by software to turn Timer/counter on/off.
Interrupt 1 edge flag.
Both edges generate flag. Set by hardware when external
interrupt edge detected. Cleared by hardware when interrupt processed.
Interrupt 1 type control bit.
Set/cleared by software to specify edge/low level
triggered external interrupts.
Interrupt 0 Edge l flag.
Set by hardware when external interrupt edge detected.
Cleared by hardware when interrupt processed.
Interrupt 0 type flag.
Set/cleared by software to specify falling edge/low level
triggered external interrupts.
