I just started writing a C application for the Cygnal C8051F125 and am having difficulty setting/viewing the paged SFR's Here's a simple example in C code: SCON0=0x50; SCON1=0x40; Compiles fine, but when when I open the disassembly window, these 2 statements get translated to: MOV SCON0(0x98),#0x50 MOV SCON0(0x98),#0x40 i.e., both statements modify SCON0. This is confirmed by opening the peripheral window and examining Serial port 1 and 2 --- SCON1 never changes (?????) I understand the SFRs on the chip are spread over 5 pages, sharing common "base addresses" (0x98 in this case), but how do I access a specific page? And how do I view the different pages in the memory window? This CAN'T be a bug, so what am I doing wrong? Thanks, Joe
