There are 29 possible status codes, listed in
the status code
and the IFLG bit in the I2Cx_CTL register is not set. All other status codes correspond to
a defined state of the I
When the device enters each of these states, the corresponding status code appears in this
register and the IFLG bit in the I2Cx_CTL register is set. When the IFLG bit is cleared,
the status code returns to
