Hello, I would like to use S9KEA64P64 to connect TJA1051T for CAN communication, and complete all functions in normal mode, but I pull up the S foot of JA1051T to make it run in Silent mode and cannot receive data, please tell me the reason for the problem, thank you!

Hi,

I do not know S9KEA64P64, but from the KEA64 RM it seems there is no CAN module. 

Generally, it could be caused if your MCU is the only one who acknowledge the message. In silent mode transmitter is disabled so MCU cannot ACK message and CAN module does not receive/store non-ACKed message. 

BR, Petr
