device ID registers of I2Cx.
Description
Master Serial Clock Enable Bit.
Loop-Back Enable Bit.
Start Back-Off Disable Bit.
Hardware General Call Enable. When this bit and Bit 3 are set, and have received a general call (Address 0x00) and a data byte, the
device checks the contents of the I2C0ALT against the receive register. If the contents match, the device has received a hardware
general call. This is used if a device needs urgent attention from a master device without knowing which master it needs to turn to.
This is a “to whom it may concern” call. The ADuC7128/ADuC7129 watch for these addresses. The device that requires attention
embeds its own address into the message. All masters listen and the one that can handle the device contacts its slave and acts
appropriately. The LSB of the I2C0ALT register should always be written to a 1, as per the I
General Call Enable Bit.

Address
Set by user to enable generation of the serial clock in master mode.
Cleared by user to disable serial clock in master mode.
Set by user to internally connect the transition to the reception to test user software.
Cleared by user to operate in normal mode.
Set by user in multimaster mode. If losing arbitration, the master immediately tries to retransmit.
Cleared by user to enable start back-off. After losing arbitration, the master waits before trying to retransmit.
Set this bit to enable the slave device to acknowledge an I
bit. If it receives a 0x06 (reset and write programmable part of slave address by hardware) as the data byte, the I
the I
sets on any general call. The user must take corrective action by setting up the I

call. The user must take corrective action by reprogramming the device address.
