Table 11-24. I2CFFRX Register Field Descriptions (continued)
Bit Field Type Reset Description
4-0 RXFFIL R/W 0h
Receive FIFO interrupt level.
These bits set the status level that will set the receive interrupt flag.
When the RXFFST4-0 bits reach a value equal to or greater than
these bits, the RXFFINT flag is set. This will generate an interrupt if
the RXFFIENA bit is set.
Note: Since these bits are reset to zero, the receive FIFO interrupt
flag will be set if the receive FIFO operation is enabled and the I2C
is taken out of reset. This will generate a receive FIFO interrupt if
enabled. To avoid this, modify these bits on the same instruction as
or prior to setting the RXFFRST bit. Because the I2C on this device
has a 16-level receive FIFO, these bits cannot be configured for an
interrupt of more than 16 FIFO levels.
Reset type: SYSRSn
