Hi, I meet a problem that the chip enter COMMAND_TIMEOUT state. This happens when I use llcc68_write_buffer with data longer than 4 bytes, the datasheet said that COMMAND_TIMEOUT is caused by an internal watchdog, and this watchdog can be disabled by the host, but I can't find any description about this watchdog and any opcode to disable it.

Do you have any idea about how to debug this problem?

BTW, I've tried SPI frequency from 10M to 16MHz, and that didn't make any difference on this problem
