IIC module is in the master mode.
If the AA bit is reset during a transfer, the IIC module will transmit the last byte of the
transfer and enter state 0xC0 or 0xC8. The IIC module is switched to the “not
addressed” slave mode and will ignore the master receiver if it continues the transfer.
Thus the master receiver receives all 1s as serial data. While AA is reset, the IIC
module does not respond to its own slave address or a general call address.
However, the I
