SC614 Slave Address

Following a start condition, the master must output the address of the slave it is accessing. The most significant six

bits of the slave address are the device type identifier (ID). For the SC614 this is fixed at 111000[ASEL]. The next

significant bit addresses a particular device. A system can have up to two SC614 devices on the same bus. The

two addresses are defined by the state of the ASEL input (see Table below).
