H. Interrupts
The W78C354 has six interrupt sources. Five (except INT1, at vector address 0013H) are identical to
those in the 80C51 series, while the sixth (at vector address 002BH) is newly added. All the interrupt
sources and the corresponding interrupt vector addresses for the W78C354 are described in the
following table:
SOURCE
