When using the I2C client with
DMA, an address match will cause the address Interrupt flag (INTFLAG.ADDRMATCH) to be
raised. After the interrupt has been serviced, data transfer will be performed through
DMA.
The I2C client generates the
following requests:
- Write data received (RX): The request
is set when host write data is received. The request is cleared when DATA is read.
- Read data needed for transmit (TX): The
request is set when data is needed for a host read operation. The request is cleared
when DATA is written.
