Timer 1 overflow flag.
Not used for interrupt control.
Timer 0 overflow flag.
Not used for interrupt control.
Interrupt 1 edge flag is set by hardware when the falling edge on external
interrupt int1 is observed. Cleared when an interrupt is processed.
Interrupt 1 type control bit. 1 selects falling edge and 0 selects low level for
input pin to cause an interrupt.
Interrupt 0 edge flag is set by hardware when the falling edge on external
interrupt int0 is observed. Cleared when an interrupt is processed.
Interrupt 0 type control bit. 1 selects falling edge and 0 sets low level for input
pin to cause interrupt.
I3FR
External interrupt 3 failing/rising edge flag.
I3FR = 0 external interrupt 3 negative transition active.
I3FR = 1 external interrupt 3 positive transition active.
External interrupt 3 failing/rising edge flag.
I2FR = 0 external interrupt 3 negative transition active.
I2FR = 1 external interrupt 3 positive transition active.
