hi how do we interface a 8251 uart with st10f168 on a keil board. thanks
The fastest I/O would be through the external bus. Connect it this way:
8251 ST10F168 ------------------------------ CS CSx - any unused CS RD RD WR WR C/D Ax - any address pin RESET any general purpose output CLK clock generator: PWM or CapCom
