Hello: I experienced a problem with TJA 1145
I'm able to put it to sleep, but I want it to wake up via a specific signal inside message 0x3A0, so I tried to set Frame control register to 0x48, which according to my understanding, it should check all 8 data bytes in 0x3C0 based on my data mask setting. Then I set the data masks all to 00:
#define PNDMMask0 0xD000
#define PNDMMask1 0xD200
#define PNDMMask2 0xD400
#define PNDMMask3 0xD600
#define PNDMMask4 0xD800
#define PNDMMask5 0xDA00
#define PNDMMask6 0xDC00
#define PNDMMask7 0xDE00
According to the datasheet, if I set them all to 00, it should never wake up. however, I'm able to wake it up with all the following messages.
0x3A0: 00 00 00 00 00 00 00 00,
0x3A0: 00 00 00 00 00 00 00,
0x3A0: 00 00
Do you know what I did wrong here?
Thanks!
