2. When an SCK
Note that special care is also needed here to avoid an intermediate level of voltage from being
applied to SCK
Caution on Switching TxD Function: If pin TxD is used as a data output pin by SCI3 in
synchronous mode and is then switched to a general input/output pin (a pin with a different
function), the pin outputs a high level signal for one system clock ( ) cycle immediately after it is
switched.

When stopping data transfer,
a. Issue one instruction to clear bits TE and RE to 0 and to set bits CKE1 and CKE0 in SCR3
b. Clear bit COM in SCR3 to 0
c. Clear bits CKE1 and CKE0 in SCR3 to 0
to 1 and 0, respectively.
