... Yes The ROMless devices, 80C32, 80C51FA, and 80C51RA+ can address up to 64K of external memory. All the devices have four 8-bit I/O ports, three 16-bit timer/event counters, a multi-source, four-priority-level, nested interrupt structure, an enhanced UART and on-chip oscillator and timing circuits. For systems that require extra memory capability up to 64k bytes, each can be expanded using standard TTL-compatible memories and logic ...

... Interrupt Priority Structure The 8XC51FA/FB/FC and 8XC51RA+/RB+/RC+/RD+ have a 7-source four-level interrupt structure (see Table 8). The 80C52/54/58 and 80C32 only have a 6-source four-level interrupt structure because these devices do not have a PCA. There are 3 SFRs associated with the four-level interrupt. They are the IE, IP, and IPH. (See Figures 10, 11, and 12.) The IPH (Interrupt Priority High) register makes the four-level interrupt structure possible ...
