Interrupt Enable flag Control
The interrupt enable flag corresponding to the data specified by I7-I0 is
controlled:
I0~I7
I0 = 1
Operation
The IEF0 is set so that interrupt 0 (overflow from the
divider 0) is accepted.
I1 = 1
The IEF1 is set so that interrupt 1 (underflow from the
Timer 0) is accepted.
I2 = 1
The IEF2 is set so that interrupt 2 (signal change at port
RC) is accepted.
I3 Reserved
I4 = 1
The IEF4 is set so that interrupt 4 (overflow from the
divider 1) is accepted for W741C260 body;
the IEF4 is set so that interrupt 4 (falling edge signal
at the INT pin) is accepted for the W741C250 body.
I5 & I6 Reserved
The IEF7 is set so that interrupt 7 (underflow from the
I7 = 1 _{Timer 1) is accepted.}
