Hello I'm using following code to setup my LINFLEX1 into uart mode and 19200bps. The problem is that via the debugger I can see that procesor set the LINFLEX1.LINFBRR.B.DIV_F = 0x05 but didn't set up the integer part in LINFLEX1.LINIBRR.B.IBR = 0xD0; Linflex is during this step still in initialization mode but the register value doesn't change even when I try to write it in debug session in eclipse based codewarrior manually.
Thank you in advance for any ideas.
Linflex initialization code follows:
LINFLEX1.LINCR1.R &= ~(1<<LINFLEX1.LINCR1.B.SLEEP); /* Put LINFlex hardware in init mode */
LINFLEX1.LINCR1.R |= (1<<LINFLEX1.LINCR1.B.INIT); /* Put LINFlex hardware in init mode */
while(LINFLEX1.LINSR.B.LINS != 0x01) { } /* Wait for the transition to initialization mode*/
/*Set up baud rate for UART - LINFLEX1 - default to 19200bps*/
LINFLEX1.LINFBRR.B.DIV_F = 0x05;
LINFLEX1.LINIBRR.B.IBR = 0xD0;
/*Setup UART mode*/
LINFLEX1.UARTCR.R |= (1<<LINFLEX1.UARTCR.B.UART); /*Enable UART mode*/
LINFLEX1.UARTCR.R = 0x33; /*8-bit data, Enable receive, Enable transmit*/
/*Configure ports*/
SIUL.PCR[8].R = 0x0103; /* MPC56xxE: Configure port A8 as LIN1RX */
SIUL.PCR[9].R = 0x0C00; /* MPC56xxE: Configure port A9 as LIN1TX */
/*Back to normal mode*/
LINFLEX1.LINCR1.R = 0x90; /* Put LINFlex hardware in normal mode */
while(LINFLEX1.LINSR.B.LINS != 0) { } /* Wait for hardware to go to normal/sleep mode */
