I2C ADDRESS REGISTER
Bit [7:1]: SLAVE_ADDR Slave Address
SLAVE_ADDR is not affected by the IIC module hardware. The contents of this
register are irrelevant when IIC module is in a master mode. In the slave mode, the
bits 7:1 must be loaded with the micro controller’s own slave address. These bits
correspond to the 7-bit slave address which will be recognized on the incoming data
stream from the I

Next Action Taken
Switched to “not addressed” SLV mode; no
recognition of own SLA or general call
address.
Switched to “not addressed” SLV mode;
own SLA will be recognized; general call
address will be recognized if ADR(0) =’1’.
Switched to “not addressed” SLV mode; no
recognition of own SLA or general call
address. A START condition will be
transmitted when the bus becomes free.
