Notes: XTAL1 XTAL2 original device pins were replaced with (clock) input signal. clock frequency value limitations during functional simulation. RST, PSEN signals behave exactly same original device compatible with Intel 8051 standard. synthesizable model, each bidirectional defined core interface separated VHDL ports. Optionally, using Aldec VHDL/Verilog Interface, merged bidirectional VHDL port. behavioral model bidirectional ports.
