13.3.1.7 Data Reception Mode
13.3.1.8 Stop Condition
Data receive mode completed
(move to control register
setting wait state)
Data receive mode start
Transmit acknowledgment value of I
2
C
master 0 control register
Transmit acknowledgment signal of I2MnCON register
through hardware
I2MnACT bit: Acknowledgment value
Transmitted acknowledgment value is stored in I2MnACR
bit of I2MnSTAT register
Store each bit of received data
in shift register (8-bit) one by one
Value (receive data) input to I2CMn_SDA pin
is stored in synchronization with rising edge of
transfer clock input to I2CMn_SCL pin in MSB first
I
2
C master 0 control register (I2MnCON) setting wait state
Store data in I
2
C master 0 receive
register
Received data is stored in the I2MnRD register from the shift
register after acknowledgment signal is transmitted
I2MnR7 to I2MnR0 bits: 8-bit receive data
Stop condition completed
(move to start condition or I
2
C
operation stop)
Stop condition start
Stop condition request
Set I2MnSP bit of I2MnCON register to “1”.
Output stop condition waveforms to 2CMn_SDA and
I2CMn_SCL pins.
Generate I
2
C bus master 0 interrupt
I2CMnIN is generated
After the stop condition waveform is output,
an interrupt is generated through hardware
Move to start condition or I
2
C operation stop (I2MnEN = 1)
