TF1 Timer 1 overflow flag.
TR1 Not used for interrupt control.
TF0 Timer 0 overflow flag.
TR0 Not used for interrupt control.
IE1 Interrupt 1 edge flag is set by hardware when the falling edge on external
interrupt int1 is observed. Cleared when an interrupt is processed.
IT1 Interrupt 1 type control bit. 1 selects falling edge and 0 selects low level for
input pin to cause an interrupt.
IE0 Interrupt 0 edge flag is set by hardware when the falling edge on external
interrupt int0 is observed. Cleared when an interrupt is processed.
IT0 Interrupt 0 type control bit. 1 selects falling edge and 0 sets low level for input
pin to cause interrupt.
