Description
When FIFO becomes empty while FEIE = 1 and write data
is transmitted. (When the FIFO_EMPTY bit in CSTR is set.)
[Clearing condition]
Write 0 after reading FEI = 1.
[Setting condition]
When FIFO becomes full while FFIE = 1 and read data is
received. (When the FIFO_FULL bit in CSTR is set.)
[Clearing condition]
Write 0 after reading FFI = 1.
[Setting condition]
When the CRC status is received while DRPIE = 1.
[Clearing condition]
Write 0 after reading DRPI = 1.
[Setting condition]
When the number of bytes of data transfer specified in
TBCR ends while DTIE = 1.
[Clearing condition]
Write 0 after reading DTI = 1.
[Setting condition]
When command response reception ends while CRPIE = 1.
[Clearing condition]
Write 0 after reading CRPI = 1.
[Setting condition]
