Change of FL (FIFO Limit Alarm) Condition Interrupt Status - Ch n:
This RESET-upon-READ bit-field indicates whether or not the Change of FL
Condition Interrupt (for Channel n) has occurred since the last read of this
register.
0 - Indicates that the Change of FL Condition Interrupt has NOT occurred
since the last read of this register.
1 - Indicates that the Change of FL Condition Interrupt has occurred since
the last read of this register.
