Section 16 Serial Communication Interface with FIFO (SCIF)
1. SCIF status check and transmit data write:
2. Serial transmission continuation procedure:
3. Break output at the end of serial
Read the serial status register (SCFSR)
and check that the TDFE flag is set to 1,
then write transmit data to SCFTDR, read 1
from the TDFE and TEND flags, then clear
these flags to 0.
The number of data bytes that can be
written is 16 – (transmit trigger set number).
To continue serial transmission, read 1
from the TDFE flag to confirm that writing is
possible, then write data to SCFTDR, and
then clear the TDFE bit to 0.
transmission:
To output a break in serial transmission,
clear the port data register (DR) to 0 before
clearing the TE bit in SCSCR to 0, and then
specify the TxD pin as an output port by the
PFC.
In steps 1 and 2, it is possible to ascertain
the number of data bytes that can be
written from the number of transmit data
bytes in SCFTDR indicated by the upper 8
bits of SCFDR.
