Note1: It is not required to read the status as these data are stored in different registers.
As the data will be updated, read the register before the next communication
frame.
Note2: Do not read RDB when RDBE = 1.
The routine for slave receive and multiaddress receive is the same as that of master receive but the status
code is different. Please refer to section 13.5.2 for the status code of slave receive and multiaddress
receive.
