I can use twi driver to config MCP23x17, and si5358. 

But I want to config the other device , it's can't config.

I check TWI register found the  TWI_MSTRSTAT.LOSTARB bit is "1" and TWI_ISTAT.MERR bit is "1".

I also try wrtie register  to operate TWI device, but failed.

Device address is 0x22, and 2nd byte is 0x21 and no data read back.
