I0 = 1
I1 = 1
I2 = 1
I3 = 1
I4 = 1
I5 & I6
The IEF0 is set so that interrupt 0 (overflow from Divider 0)
is accepted.
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
RC) is accepted.
The IEF4 is set so that interrupt 4 (falling edge signal on
