[1] When data is received, a receive data ready
interrupt occurs. Go to the data reception flow
by using this interrupt trigger.
[2] Confirm that the BI, FE, PE, and OE flags in
FLSR are all cleared. If any one of these flags
is set to 1, perform error processing.
[3] Read the receive FIFO.
[4] Check the DR flag in FLSR. When the DR flag
is cleared and all of the data has been read, data
reception
is
complete.
