mapping SFR space

How would I locate a structure to coincide with the beginning of SFR space for the 8051? address 0x80 of directly assessible data memory. We are using a core8051 (inside an FPGA), and the core8051...

'c' casting in sfr space data

i have an unusual problem which i'd very much like some help with. i'm using floating point notation in my project, however it is a defacto 16 bit floating point system with a hardware engine doing...
abort message when accessing sfr space

Hi. I'm using the LPC2103 from NXP. When I want to set the SPI1 register SSPCR0 (which is located at address 0xE0068000) the simulator responds with a "Data abort". The same situation occurs...
