FUNCTIONAL DESCRIPTION
The W78LE51 architecture consists of a core controller surrounded by various registers, five general
purpose I/O ports, 128 bytes of RAM, two timer/counters, and a serial port. The processor supports
111 different opcodes and references both a 64K program address space and a 64K data storage
space.
New Defined Peripheral
In order to be more suitable for I/O, an extra 4-bit bit-addressable port P4 and two external interrupt
INT2
, INT3 has been added to either the PLCC or QFP 44 pin package. And description follows:
1.
INT2
/ INT3
Two additional external interrupts,
INT2
and INT3 , whose functions are similar to those of external
interrupt 0 and 1 in the standard 80C52. The functions/status of these interrupts are determined/
shown by the bits in the XICON (External Interrupt Control) register. The XICON register is bit-
