(8) Bit 7: Communication mode specification bit

(master/slave specification bit: MST)

This bit is used for master/slave specification for data communica-

tion. When this bit is “0,” the slave is specified, so that a START

condition and a STOP condition generated by the master are received,

and data communication is performed in synchronization with the

clock generated by the master. When this bit is “1,” the master is

specified and a START condition and a STOP condition are gener-

ated, and also the clocks required for data communication are gen-

erated on the SCL.

The MST bit is cleared to “0” in one of the following conditions.

• Immediately after completion of 1-byte data transmission when

arbitration lost is detected

• When a STOP condition is detected.

• When occurence of a START condition is disabled by the START

condition duplication preventing function (Note).

• At reset

Note: The START condition duplication prevention function disables the START

condition generation, reset of bit counter reset, and SCL output, when

the following condition is satisfied:

a START condition is set by another master device.
