Output Active Trigger
When the quantity of receive data in receive FIFO data
register (SCFRDR) becomes more than the number
shown below,
RTS
signal is set to high.

Receive FIFO Data Trigger
•
Set the quantity of receive data which sets the receive
data full (RDF) flag in the serial status register
(SCFSR). The RDF flag is set to 1 when the quantity
of receive data stored in the receive FIFO register
(SCFRDR) is increased more than the set trigger
number shown below.

Note: In clock synchronous mode, to transfer the
receive data using DMAC, set the receive trigger
number to 1. If set to other than 1, CPU must
read the receive data left in SCFRDR.
