Interrupt System
C515
Special Function Register T2CON (Address C8H)
Reset Value : 00H
The shaded bits are not used for interrupt control.
The external interrupt 2 (INT2) can be either positive or negative transition-activated depending on
bit I2FR in register T2CON. The flag that actually generates this interrupt is bit IEX2 in register
IRCON. lf an interrupt 2 is generated, flag IEX2 is cleared by hardware when the service routine is
vectored to.
The external interrupt 3 (INT3) can be either positive or negative transition-activated, depending
on bit I3FR in register T2CON. The flag that actually generates this interrupt is bit IEX3 in register
IRCON. In addition, this flag will be set if a compare event occurs at pin P1.0/INT3/CC0, regardless
of the compare mode established and the transition at the respective pin. The flag IEX3 is cleared
by hardware when the service routine is vectored to.

Function
I3FR
External interrupt 3 rising/falling edge control flag
If I3FR = 0, the external interrupt 3 is activated by a falling edge at P1.0/INT3/CC0.
If I3FR = 1, the external interrupt 3 is activated by a rising edge at P1.0/INT3/CC0.
I2FR
External interrupt 2 rising/falling edge control flag
If I2FR = 0, the external interrupt 2 is activated by a falling edge at P1.4/INT2.
If I2FR = 1, the external interrupt 2 is activated by a rising edge at P1.4/INT2.
