Selection of 16 internal clocks (in master mode)
Direct bus drive (SCL/SDA pin)
Automatic switching from formatless mode to I
Address match: When any slave address matches or the general call address is received in
slave receive mode with I
arbitration)
Start condition detection (in master mode)
Stop condition detection (in slave mode)
Four pins—P52/SCL0, P97/SDA0, P86/SCL1, and P42/SDA1 —(normally NMOS push-
pull outputs) function as NMOS open-drain outputs when the bus drive function is selected.
Formatless operation (no start/stop conditions, non-addressing mode) in slave mode
Operation using a common data pin (SDA) and independent clock pins (VSYNCI, SCL)
Automatic switching from formatless mode to I
