Pins P5
serial transmit data (TxD). When used for TxD output, these pins are unaffected by the values in
P5DDR and P5DR, and their MOS pull-ups are automatically turned off.
Pins P5
receive data (RxD). When used for RxD input, these pins are unaffected by P5DDR and P5DR,
except that software can turn on their MOS pull-ups by clearing their data direction bits to 0 and
setting their data bits to 1.
Pins P5
input or output (SCK). When used for SCK output, these pins are unaffected by P5DDR and P5DR.
When these pins are used for SCK input, software can turn on their MOS pull-ups by clearing their
data direction bits to 0 and setting their data bits to 1.
Reset and Hardware Standby Mode: P5DDR and P5DR are cleared to all 0 and the serial control
registers are initialized. All pins are placed in the input port (high-impedance) state with the MOS
pull-ups off.
Software Standby Mode: The serial control registers are initialized but P5DDR and P5DR remain
in their previous states. All pins become input or output port pins depending on the setting of
P5DDR. Output pins output the values in P5DR. The MOS pull-ups of input pins are on or off
depending on the values in P5DR.
Figures 5-8 to 5-10 show schematic diagrams of port 5.
