Multi-Master IIC Interface (MMIIC)
14.5.4 Multi-Master IIC Status Register (MMSR)
Technical Data
188
Address:
MMRXIF — Multi-Master IIC Receive Interrupt Flag
Reset:
Read: MMRXIF
Write:
This flag is set after the data receive register (MMDRR) is loaded with
a new received data. Once the MMDRR is loaded with received data,
no more received data can be loaded to the MMDRR register until the
CPU reads the data from the MMDRR to clear MMRXBF flag.
MMRXIF generates an interrupt request to CPU if the MMIEN bit in
MMCR is also set. This bit is cleared by writing "0" to it or by reset; or
when the MMEN = 0.
1 = New data in data receive register (MMDRR)
0 = No data received
