Oregano 8051 register R0 and R1 are not direct accessable

nanswamy n over 14 years ago

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
