各位先進
在18F2680的Errata中，有提到ECAN的一個BUG，裡面有一段SAMPLE CODE如下，我是用Mode1的模式 If (RXBnOVFL == 1) // Has an overflow occurred? { If (TXREQ == 1)// Is a transmission pending? { TXREQ = 0; // Clear transmit request If (TXABT == 1)// Store transmission aborted tatus value MyFlag = 1; } } Temp_RXREG = RXBx; // Read receive buffer If (MyFlag) // Was previous transmission aborted? { TXREQ = 1; // Set transmit request MyFlag = 0; // Reset stored transmission aborted status } 在MODE 1裡面，有3個TX Buffer及2個RX Buffer 當發生錯誤時，RXBnOVFL的Flag會=1 但是TXREQ在TXB0CON、TXB1CON及TXB2CON都有 而RXBn有RXB0及RXB1兩個 所以想請問各位先進，有沒有人知道上面那一段SAMPLE該如何寫，才是正確的？
