Port 3 pins with alternate output functions are:
T6OUT, T3OUT, TxD0, BHE and CLKOUT.
When the on-chip peripheral associated with
a Port 3 pin is configured to use both the alternate
input and output function, the descriptions above
apply to the respective current operating mode.

The direction must be set accordingly. Port 3 pins
with alternate input/output functions are: MTSR,
MRST, RxD0 and SCLK.
Note: Enabling the CLKOUT function automati-

cally enables the P3.15 output driver. Set-
ting bit DP3.15=’1’ is not required.
