Hello Upendra

Extrapolating from the Processor Expert bean, I got this initialization
code (with a 15 MHz cpu clock) for 57600 baud, 8 data bits, 1 stop bit,
no parity, no interrupts:

/* SCI0_SCICR:
LOOP=0,SWAI=0,RSRC=0,M=0,WAKE=0,POL=0,PE=0,PT=0,TEIE=0,TIIE=0,RFIE=0,REI
E=0,TE=1,RE=1,RWU=0,SBK=0 */
setReg(SCI0_SCICR,12); /* Set the SCI configuration */
setReg(SCI0_SCIBR,16); /* Set prescaler bits */

(write 0 to SCISR to clear all error flags) On 11.06.2005, at 07:42, upendra mahida wrote:
