Read SSR and check that the TDRE
flag is set to 1, set the MPBT bit in
SSR to 0 or 1, then write transmit
data to TDR. When data is written to
TDR, the TDRE flag is automatically
cleared to 0.
To continue serial transmission, be
sure to read 1 from the TDRE flag to
confirm that writing is possible, then
write data to TDR. When data is
written to TDR, the TDRE flag is
automatically cleared to 0.
To output a break in serial
transmission, set the port PCR to 1,
clear PDR to 0, then clear the TE bit
in SCR3 to 0.
