FAQ：BDLC?ByteDataLinkController

中斷：

在不使用CANO的狀況下，根據(jù)你口勺對未使用中斷的編碼方式，填滿CANO中斷向量($FFBO-SFFB7),

在不使用BDLC的狀況下，根據(jù)你的對未使用中斷的編碼方式，填滿BDLC中斷向量($FFC2,$FFC3).

接工

在不使用CANO的狀況下,CANO帶TXCANO,RXCANO功能的引腳在PJ7,PJ6,PM5,

PM4,PM3,PM2,PM1和PMO接口上無效。

在不使用BDLC的狀況下,BDLC功能引腳TXB,RXB在PM1和PMO接口上無效。

FAQ：各引腳功能應(yīng)當(dāng)先有個(gè)簡介？

在不使用CANO的狀況下,嚴(yán)禁寫ModuleRoutingRegisterMODRR1和MODRRO位。
