HI everyone!
I am workinf with Silabs 8051F020, and I need to use the uart1 shift register mode (mode 0). Everything seems to work fine, except that when I try to read the SBUF1 register and load it to a software buffer, i don't get anything. I am debugging on software, and loading myself the sbuf1 reg with a byte (0x51), and when i set the interrupt flag, it recognises a reception, but when it gets to the point
buffer = SBUF1;
i get 0x00 on buffer. i also checked that SBUF1 is loaded by posing the mouse over it's name Any ideas will be appreciated
Thanks
