Section 15 Serial Communication Interface (SCI, IrDA)
SCI initialization:
The TxD pin is automatically
designated as the transmit data
output pin.
After the TE bit is set to 1,
a frame of 1s is output, and
transmission is enabled.
SCI status check and transmit
data write:
Read SSR and check that the
TDRE flag is set to 1, then write
transmit data to TDR. Set the
MPBT bit in SSR to 0 or 1.
Finally, clear the TDRE flag to 0.
Serial transmission continuation
procedure:
To continue serial transmission,
be sure to read 1 from the TDRE
flag to confirm that writing is
possible, then write data to TDR,
and then clear the TDRE flag to
0. Checking and clearing of the
TDRE flag is automatic when the
DMAC or DTC is activated by a
transmit-data-empty interrupt
(TXI) request, and data is written
to TDR.
Break output at the end of serial
transmission:
To output a break in serial
transmission, set the port DDR to
1, clear DR to 0, then clear the
TE bit in SCR to 0.
