TCON.7
TF1
Timer 1 overflow flag.
TCON.6
TR1
Not used for interrupt control.
TCON.5
TF0
Timer 0 overflow flag.
TCON.4
TR0
Not used for interrupt control.
TCON.3
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.
TCON.2
IT1
Interrupt 1 type control bit. 1 selects falling edge and 0 selects low level for
input pin to cause an interrupt.
TCON.1
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.
TCON.0
IT0
Interrupt 0 type control bit. 1 selects falling edge and 0 sets low level for input
pin to cause interrupt.
