IC_TXFLR
Name: I2C Transmit FIFO Level Register
Size: TX_ABW + 1
Address Offset: 0x74
Read/Write Access: Read
This register contains the number of valid data
entries in the transmit FIFO buffer. It is cleared
whenever:
- The I2C is disabled
- There is a transmit abort that is, TX_ABRT bit is
set in the IC_RAW_INTR_STAT register
- The slave bulk transmit mode is aborted
The register increments whenever data is placed into
the transmit FIFO and decrements when data is
taken from the transmit FIFO.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
