Oregano 8051 register R0 and R1 are not direct accessable

nanswamy n

HI ,

I wanted to use the oregano 8051 free core and evalaute for using in a design.

wanted to simulate to check for the 8051 instrution set.

I find that Oregano 8051 MCU register R0 and R1 are not direct accessable.

example: MOV R0,#80H does not work.

Is that an issue?

Thanks in advance
Swamy

    The real problem is with people who assume that "free" means free of all costs in terms of time, money, effort, etc - but that is not the spirit of Open-Source!

    As Oregano themselves say:

    "We kindly ask you to send us a brief feedback about your successfully implementation of the Oregano Systems 8051 IP core in your FPGA or ASIC design. Please send us either a simple email or use the 8051 IP core feedback form (PDF-File)."

    In other words, they expect you to contribute
