Timer 1 overflow flag
: set by hardware on timer/counter overflow. Cleared when
interrupt is processed.
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 when
interrupt is processed.
Timer 0 run control bit
: set/cleared by software to turn timer/counter ON/OFF.
Interrupt 1 edge flag
: set by hardware when external interrupt is detected. Cleared
when interrupt is processed.
Interrupt 1 type control bit
: set/cleared by software to specify falling edge/LOW level
triggered external interrupt.
Interrupt 0 edge flag
: set by hardware when external interrupt is detected. Cleared
when interrupt is processed.
Interrupt 0 type control bit
: set/cleared by software to specify falling edge/LOW level
triggered external interrupt.
