14.3.1.7 Stop Condition
Communication is started when communication mode is selected by using the I
bus 0 slave address register, and “1” is written to the I20ST bit of the I2C bus 0 control register (I2C0CON).
When “1” is written to the I20ST bit of the I
I20ST bit is “0”), communication is started and the start condition waveform is output to the SDA and SCL pins.
After execution of the start condition, the LSI shifts to slave address transmit mode.
When “1” is written to the I20RS and I20ST bits of the I
(the I20ST bit is “0”), the restart condition waveform is output to the SDA and SCL pins.
After execution of the restart condition, the LSI shifts to slave address transmit mode.
In slave address transmit mode, the values (slave address and data communication direction) of the I
address register (I2C0SA) are transmitted in MSB first, and finally, the acknowledgment signal is received in the
I20ACR bit of the I
At completion of acknowledgment reception, the LSI shifts to the I
state (control register setting wait state).
The value of I2C0SA output from the SDA pin is stored in I2C0RD.
In data transmit mode, the value of I2C0TD is transmitted in MSB first, and finally, the acknowledgment signal is
received in the I20ACR bit of the I
At completion of acknowledgment reception, the LSI shifts to the I
state (control register setting wait state).
The value of I2C0TD output from the SDA pin is stored in I2C0RD.
In data receive mode, the value input in the SDA pin is received synchronously with the rising edge of the serial clock
output to the SCL pin, and finally, the value of the I20ACT bit of the I2C bus 0 control register (I2C0CON) is output.
At completion of acknowledgment transmission, the LSI shifts to the I
state (control register setting wait state).
The data received is stored in I2C0RD after the acknowledgment signal is output. The acknowledgment signal output
When the LSI shifts to the control register setting wait state, an I
In the control register setting wait state, the transmit flag (I20ER) of the I
acknowledgment receive data (I20ACR) are confirmed and at data reception, the contents of I2C0RD are read in the
CPU and the next operation mode is selected.
When “1” is written to the I20ST bit in the control register setting wait state, the LSI shifts to the data transmit or
receive mode. When “1” is written to the I20SP bit, the LSI shifts to the stop condition. When “1” is written to the
I20RS bit, the operation shifts to the restart condition.
In the stop condition, the stop condition waveform is output to the SDA and SCL pins. After the stop condition
waveform is output, an I
