Fig. 67 Structure of I2C control register
[I2C Control Register (S1D)] 001416
The I2C control register (S1D: address 001416) controls data com-
munication format.
Bits 0 to 2: Bit counter (BC0–BC2)
These bits decide the number of bits for the next 1-byte data to be
transmitted. The I2C interrupt request signal occurs immediately
after the number of count specified with these bits (ACK clock is
added to the number of count when ACK clock is selected by ACK
clock bit (bit 7 of S2, address 001516) have been transferred, and
BC0 to BC2 are returned to “0002”.
Also when a START condition is received, these bits become
“0002” and the address data is always transmitted and received in
8 bits.
Bit 3: I2C interface enable bit (ES0)
This bit enables to use the multi-master I2C-BUS interface. When
this bit is set to “0,” the use disable status is provided, so that the
SDA and the SCL become high-impedance. When the bit is set to
“1,” use of the interface is enabled.
When ES0 = “0,” the following is performed.
PIN = “1,” BB = “0” and AL = “0” are set (which are bits of the I2C
status register, S1, at address 001316 ).
Writing data to the I2C data shift register (S0: address 001116) is
disabled.
Bit 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 address data is recognized. When a match is found between
a slave address and address data as a result of comparison or
when a general call (refer to “I2C Status Register,” bit 1) is re-
ceived, transfer processing can be performed. When this bit is set
to “1,” the free data format is selected, so that slave addresses are
not recognized.
Bit 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 slave address
registers 0 to 2 are compared with address data. When this bit is
set to “1,” the 10-bit addressing format is selected, and all the bits
of the I2C slave address registers 0 to 2 are compared with ad-
dress data.
Bit 7: I2C-BUS interface pin input level selection bit (TISS)
This bit selects the input level of the SCL and SDA pins of the
multi-master I2C-BUS interface.
