Description
FIFO Empty Interrupt Flag
0: No interrupt
[Clearing condition]
Write 0 after reading FEI = 1.
(Writing 1 is invalid)
1: Interrupt requested
[Setting condition]
When FIFO becomes empty while FEIE = 1
and data is being transmitted
(when the FIFO_EMPTY bit in CSTR is set)
FIFO Full Interrupt Flag
0: No interrupt
[Clearing condition]
Write 0 after reading FFI = 1.
(Writing 1 is invalid)
1: Interrupt requested
[Setting condition]
When FIFO becomes full while FFIE = 1
and data is being received
(when the FIFO_FULL bit in CSTR is set)
