uja1169tk/f can not set partial networking

[jason_qian]

I set CPNC = 1; when I read the register (0x22), the result is 0xc0, Please tell me which registers to set, thank you

Hi Jason,

Please note that also the CWE bit should be set to 1:

The ID registers (0x27 to 0x2A) should also be configured so that UJA1169 knows which IDs are selected.

PNCOK bit should be set to 1 at the end of partial networking configuration:

I hope it helps.

Best regards,

Tomas

I set the ID is 0x1a0,  Unable to wake up uja1169 when I send this ID once, but When I send it twice in a row, can wake up  uja1169.   Why do I have to send the ID  twice in a row
