#158225 - You need to know the instruction set Responding to: ???'s previous message |
which you will find here
http://www.nxp.com/acrobat_d...UIDE_1.pdf and the internal hardware: http://www.nxp.com/acrobat_d...WARE_1.pdf I'm not quite clear what you mean. Maybe you need to know how 16bit addresses are handled? Often the data pointer register DPTR is used to handle 16bit addresses. The DPTR exists as pair of two 8bit registers, DPH and DPL, the higher and lower 8bits of this DPTR, which you will find in the Special Function Register Set. There are instructions to handle these registers or the whole DPTR. Search for "DPH", "DPL" and "DPTR" keywords in the pdf-files above. Kai |
