#152706 - SFR question |
I am a bit confused regarding 8051 and SRF's.
According to the SFR chart: Address Function ------- ---------- 0x98h SCON I thought that: 0x98h is the address of the 1st bit of SCON (RI) 0x99h is the 2nd bit of SCON (TI) 0x9Ah is the 3rd bit of SCON (RB8) 0x9bh is the 4th bit of SCON (TB8) ........... ...... Question 1 - am I correct so far? BUT if I have another look at the SFR chart I see: Address Function -------- -------- 0x99h SBUF So now I am confused. Question 2) What is address 0x99h? Thanks to all. |
