For the purposes of user software, the contents of the SMB0STA register is only defined when the SI flag is
logic 1. Software should never write to the SMB0STA register; doing so will yield indeterminate results. The
28 SMBus0 states, along with their corresponding status codes, are given in Table 1.1.

STA7-STA3: SMBus0 Status Code.
These bits contain the SMBus0 Status Code. There are 28 possible status codes; each sta-
tus code corresponds to a single SMBus state. A valid status code is present in SMB0STA
when the SI flag (SMB0CN.3) is set to logic 1. The content of SMB0STA is not defined when
the SI flag is logic 0. Writing to the SMB0STA register at any time will yield indeterminate
results.
STA2-STA0: The three least significant bits of SMB0STA are always read as logic 0 when
the SI flag is logic 1.
