Parallel Ports
The port structure of the Port 3 pins depends on their alternate function (see figures
below).
When the on-chip peripheral associated with a Port 3 pin is configured to use the
alternate input function, it reads the input latch, which represents the state of the pin, via
the line labeled “Alternate Data Input”. Port 3 pins with alternate input functions are:
T3IN and T4IN/T3EUD/T2EUD.
When the on-chip peripheral associated with a Port 3 pin is configured to use the
alternate output function, its “Alternate Data Output” line is ANDed with the port output
latch line. When using these alternate functions, the user must set the direction of the
port line to output (DP3.y=1) and must set the port output latch (P3.y=1). Otherwise the
pin is in its high-impedance state (when configured as input) or the pin is stuck at '0'
(when the port output latch is cleared). When the alternate output functions are not used,
the “Alternate Data Output” line is in its inactive state, which is a high level ('1'). Port 3
pins with alternate output functions are:
T6OUT, T3OUT, TxD0 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 automatically enables the P3.15 output driver.
Setting bit DP3.15=’1’ is not required.
