Reset Description
0x0000.00 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0
Receive FIFO Read Error
Value Description
1 An unmasked interrupt was signaled due to a receive FIFO read
error.
0 An interrupt has not occurred or is masked.
This bit is cleared by setting the RXREIC bit in the I2SIC register.
0
Receive FIFO Service Request
Value Description
1 An unmasked interrupt was signaled due to a receive FIFO
service request.
0 An interrupt has not occurred or is masked.
This bit is cleared when the level in the receive FIFO has risen to a value
greater than the value programmed in the LIMIT field in the I2SRXLIMIT
register.

0
Transmit FIFO Write Error
Value Description
1 An unmasked interrupt was signaled due to a transmit FIFO
write error.
0 An interrupt has not occurred or is masked.
This bit is cleared by setting the TXWEIC bit in the I2SIC register.
