Set clock selection in SCR3. Be sure to
clear the other bits to 0. If clock output
is selected in asynchronous mode, the
clock is output immediately after setting
bits CKE1 and CKE0. If clock output is
selected for reception in synchronous
mode, the clock is output immediately
after bits CKE1, CKE0, and RE are
set to 1.
Set the data transfer format in the serial
mode register (SMR).
Write the value corresponding to the
transfer rate in BRR. This operation is
not necessary when an external clock
is selected.
Wait for at least one bit period, then set
bits TIE, RIE, MPIE, and TEIE in SCR3,
and set bits RE or TE to 1 in SCR3.
Setting bits TE and RE enables the TXD
and RXD
mode the mark state is established when
transmitting, and the idle state waiting for
a start bit when receiving.
