R/W
R/(W)* Receive Data Ready
Section 15 Serial Communication Interface with FIFO (SCIF)
Description
Indicates that the quantity of data in the receive FIFO
data register (SCFRDR) is less than the specified
receive trigger number, and that the next data has not
yet been received after the elapse of 15 ETU from the
last stop bit in asynchronous mode. In clock
synchronous mode, this bit is not set to 1.
0: Receiving is in progress, or no receive data
[Clearing conditions]
•
•
•
1: Next receive data has not been received
[Setting condition]
•
Note:
remains in SCFRDR after receiving ended normally
DR is cleared to 0 when the chip undergoes a
power-on reset
DR is cleared to 0 when all receive data are read
after 1 is read from DR and then 0 is written.
DR is cleared to 0 when all receive data are read
after DMAC is activated by receive FIFO data full
interrupt (RXI).
DR is set to 1 when SCFRDR contains less data
than the specified receive trigger number, and the
next data has not yet been received after the
elapse of 15 ETU from the last stop bit.*
*
This is equivalent to 1.5 frames with the 8-
bit, 1-stop-bit format. (ETU: Elementary
time unit)
