Description:
1
Interrupt Enable flag Control
The interrupt enable flag corresponding to the data specified by I7−I0 is
controlled:
I0 to I5 Operation
The IEF0 is set so that interrupt 0 (overflow from Divider 0)
I0 = 1 _{is accepted.}
I1 = 1
The IEF1 is set so that interrupt 1 (underflow from Timer 0)
is accepted.
The IEF2 is set so that interrupt 2 (signal change on port
I2 = 1 _{RC) is accepted.}
I3 = 1
I4 = 1
Reserved
The IEF4 is set so that interrupt 4 (falling edge signal on
the INT pin) is accepted.
I5 & I6 Reserved
I7 = 1
The IEF7 is set so that interrupt 7 (underflow from Timer 1)
is accepted.
