Section 16 I
16.1.2
Figure 16.1 shows a block diagram of the I
Figure 16.2 shows an example of I/O pin connections to external circuits. Channel 0 I/O pins and
channel 1 I/O pins differ in structure, and have different specifications for permissible applied
voltages. For details, see section 26, Electrical Characteristics.

Wait function in slave mode (I
A wait request can be generated by driving the SCL pin low after data transfer, excluding
acknowledgement. The wait request is cleared when the next transfer becomes possible.
Three interrupt sources
Selection of 16 internal clocks (in master mode)
Direct bus drive (with SCL and SDA pins)
Automatic switching from formatless mode to I
Data transfer end (including transmission mode transition with I
reception after loss of master arbitration)
Address match: when any slave address matches or the general call address is received in
slave receive mode (I
Stop condition detection
Two pins—P52/SCL0 and P97/SDA0—(normally NMOS push-pull outputs) function as
NMOS open-drain outputs when the bus drive function is selected.
Two pins—P86/SCL1 and P42/SDA1—(normally CMOS pins) function as NMOS-only
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
