12.6.8 START/STOP Condition Detect Condi-

tions

The START/STOP condition detect conditions are shown in

Figure 12.6.11 and Table 12.6.3. Only when the 3 conditions of Table

12.6.3 are satisfied, a START/STOP condition can be detected.

Note: When a STOP condition is detected in the slave mode

(MST = 0), an interrupt request signal “IICIRQ” is generated to the

CPU.

12.6.9 Address Data Communication

There are two address data communication formats, namely, 7-bit

addressing format and 10-bit addressing format. The respective ad-

dress communication formats is described below.

(1) 7-bit Addressing Format

To meet the 7-bit addressing format, set the 10BIT SAD bit of the I2C

control register (address 00F916) to “0.” The first 7-bit address data

transmitted from the master is compared with the high-order 7-bit

slave address stored in the I2C address register (address 00F716).

At the time of this comparison, address comparison of the RBW bit of

the I2C address register (address 00F716) is not made. For the data

transmission format when the 7-bit addressing format is selected,

refer to Figure 12.6.12, (1) and (2).

(2) 10-bit Addressing Format

To meet the 10-bit addressing format, set the 10BIT SAD bit of the

I2C control register (address 00F916) to “1.” An address comparison

is made between the first-byte address data transmitted from the

master and the 7-bit slave address stored in the I2C address register

(address 00F716). At the time of this comparison, an address com-

parison between the RBW bit of the I2C address register (address

00F716) and the R/W bit which is the last bit of the address data

transmitted from the master is made. In the 10-bit addressing mode,

the R/W bit which is the last bit of the address data not only specifies

the direction of communication for control data but also is processed

as an address data bit.

When the first-byte address data matches the slave address, the

AAS bit of the I2C status register (address 00F816) is set to “1.” After

the second-byte address data is stored into the I2C data shift register

(address 00F616), make an address comparison between the sec-

ond-byte data and the slave address by software. When the address

data of the 2nd bytes matches the slave address, set the RBW bit of

the I2C address register (address 00F716) to “1” by software. This

processing can match the 7-bit slave address and R/W data, which

are received after a RESTART condition is detected, with the value

of the I2C address register (address 00F716). For the data transmis-

sion format when the 10-bit addressing format is selected, refer to

Figure 12.6.12, (3) and (4).
