Hi All , I am writing CAN Driver for mpc5777m , that is MCAN driver.I am unable to come out of interrupt routine which handles the interrupts bit (TC) Transmission completed or Receive buffer is full. For this I am enabled the
For Trasmission
M_CAN_1.TXBTIE.B.TIE = 1; // Tx Buffer Transmission Interrupt Enable
M_CAN_1.IE.B.TCE = 1; // Transmission Completed Interrupt Enable
ISR function
void MCAN_ISR(void)
{
if (M_CAN_1.IR.B.TC == 1) //Is interrupt because transmission completed
{
M_CAN_1.IR.R = 0x200; // clear interrupt flag.
------ doing something----
}
}
Control is not coming out when even TC is 0 i.e it is inside ISR function always.
