SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER
and ON-SCREEN DISPLAY CONTROLLER
(4) I2C Control Register
The I2C control register (address 00DC16) controls the data commu-
nication format.
sBits 0 to 2: Bit Counter (BC0–BC2)
These bits decide the number of bits for the next 1-byte data to be
transmitted. An interrupt request signal occurs immediately after the
number of bits specified with these bits are transmitted.
When a START condition is received, these bits become “0002” and
the address data is always transmitted and received in 8 bits.
sBit 3: I2C Interface Use Enable Bit (ESO)
This bit enables usage of the multimaster I2C BUS interface. When
this bit is set to “0,” the use disable status is provided, so the SDA
and the SCL become high-impedance. When the bit is set to “1,” use
of the interface is enabled.
When ESO = “0,” the following is performed.
PIN = “1,” BB = “0” and AL = “0” are set (they are bits of the I2C
status register at address 00F816 ).
Writing data to the I2C data shift register (address 00F616) is dis-
abled.
sBit 4: Data Format Selection Bit (ALS)
This bit decides whether or not to recognize slave addresses. When
this bit is set to “0,” the addressing format is selected, so that ad-
dress data is recognized. When a match is found between a slave
address and address data as a result of comparison or when a gen-
eral call (refer to “(5) I2C Status Register,” bit 1) is received, trans-
mission processing can be performed. When this bit is set to “1,” the
free data format is selected, so that slave addresses are not recog-
nized.
Fig. 28. I2C Control Register
sBit 5: Addressing Format Selection Bit (10BIT SAD)
This bit selects a slave address specification format. When this bit is
set to “0,” the 7-bit addressing format is selected. In this case, only
the high-order 7 bits (slave address) of the I2C address register (ad-
dress 00F716) are compared with address data. When this bit is set
to “1,” the 10-bit addressing format is selected, all the bits of the I2C
address register are compared with address data.
sBits 6 and 7: Connection Control Bits between I2C-BUS Interface
and Ports (BSEL0, BSEL1)
These bits controls the connection between SCL and ports or SDA
and ports (refer to Figure 28).

CIIC (Note 2)
Notes 1 : When using multi-master I2C-BUS interface, set bits 3 to
7 of the serial I/O mode register (address 00DE16) to “1.”
2 : CIIC is bit 2 of the serial I/O control register (address
020716) (refer to Figure 21).
