will be acknowledged. If EA=1, each
interrupt source is individually enabled
or disabled by setting or clearing its
enable bit.

Note:
To use any of the interrupts in the 80C51 Family, the
following three steps must be taken:
1. Set the
EA
(enable all) bit in the IE register to 1.
2. Set the coresponding individual interrupt enable bit in
the IE register to 1.
3. Begin the interrupt service routine at the corresponding
Vector Address of that interrupt (see below).

4. In addition, for external interrupts, pins
INT0
and
INT1
(P3.2 and P3.3) must be set to 1, and depending on
whether the interrupt is to be level or transition activated,
bits IT0 or IT1 in the TCON register may need to be set to
0 or 1.
ITX = 0 level activated (X = 0, 1)
ITX = 1 transition activated
5.
User software should not write 1s to reserved bits. These
bits may be used in future products to invoke new features.
