how do I specify in C that xdata access is to use EMI0CN instead of P2 for high byte of address xdata access
Is there a choice, or does the SiLabs chip in question just always use EMI0CN instead of P2 - in which case it should be invisible to 'C' (or even assembler?).
in which case it should be invisible to 'C' (or even assembler?). sure, except paging @ri - ..... naah, you just have to remember.
yes, you are right, what blew me was the SDCC _XPAGE (I'm doing a Keil/SDCC document)
