Hi,
Please find the salve configuration for LIN module with MPC5777M EVM board in following lines...
LINFlexD_0.UARTCR.B.UART = 0 ; // There is no meaning of LIN mode until UART bit is not reset in UARTCR register
LINFlexD_0.LINCR1.B.INIT = 1 ; // Put LINFlex hardware in init mode to come out reset that INIT bit
LINFlexD_0.LINCR1.B.SLEEP = 0 ; // Disable the request of sleep mode in LIN
while (0x1000 != (LINFlexD_0.LINSR.R & 0xF000))
{
// Wait for INIT mode of LIN module
}
LINFlexD_0.LINIBRR.B.IBR = 480 ; //baud rate
LINFlexD_0.LINFBRR.B.FBR = 0 ; //fractional baud rate
LINFlexD_0.LINCR2.R = 0x4000 ; // avoid the idle state when bit error is come
LINFlexD_0.LINTCSR.R = 0 ; // Avoid that get slave in idle state
LINFlexD_0.BIDR.B.CCS = 0x01u; // enhanced checksum for LIN Slave
LINFlexD_0.IFER.R = 0xF; // enable filters 0-3
LINFlexD_0.IFMR.R = 0x0; // filters 0 - 3 are in identifier list mode.
LINFlexD_0.IFCR[0].R = 0x1E37; // 8bytes, TX data, ID=0x37, CCS=0
LINFlexD_0.IFCR[1].R = 0x1C35; // 8bytes, RX data, ID=0x35, CCS=0
LINFlexD_0.IFCR[2].R = 0x1F36;
LINFlexD_0.IFCR[3].R = 0x1F35; // 8bytes, TX data, ID=0x35, CCS=1
// LIN configure : MME=0,BF=1,MBL=3,INIT=0,AUTO=1
LINFlexD_0.LINCR1.R = 0x00001380 ;
please make me sure that i did , is right or i have to do something else .?
