pre
#include <Nordic\reg24e1.h>
#include <stdio.h>
void Init(void){


TH1 = 243; // 19200@16MHz (when T1M=1 and SMOD=1)
CKCON |= 0x10; // T1M=1 (/4 timer clock)
PCON = 0x80; // SMOD=1 (double baud rate)
SCON = 0x52; // Serial mode1, enable receiver
TMOD = 0x20; // Timer1 8bit auto reload
TR1 = 1; // Start timer1
P0_DIR |= 0x02; // P0.1 (RxD) is an input
P0_ALT |= 0x06; // Select alternate functions on pins P0.1 and P0.2

EA=1;
}
