MOS Pull-Ups: Are available for input pins, including pins used for input of timer or interrupt
signals. Software can turn the MOS pull-up on by writing a 1 in P6DR, and turn it off by writing a
0. The pull-ups are automatically turned off for output pins.
Pins P6
output, or for input of free-running timer clock and input capture signals. When a pin is used for
free-running timer input, its P6DDR bit should be cleared to 0; otherwise the free-running timer
will receive the value in P6DR. If input pull-up is not desired, the P6DR bit should also be cleared
to 0.
Pin P6
compare signals (FTOA and FTOB) of the free-running timer. When used for FTOA or FTOB
output, these pins are unaffected by the values in P6DDR and P6DR, and their MOS pull-ups are
automatically turned off.
Pins P6
request signals (IRQ
bits should normally be cleared to 0, so that the value in P6DR will not generate interrupts.
Reset and Hardware Standby Mode: P6DDR and P6DR are cleared to all 0. Timer output and
interrupt request input are disabled. All pins are placed in the input port (high-impedance) state
with the MOS pull-ups off.
Software Standby Mode: The free-running timer control registers are initialized but P6DDR,
P6DR, and the interrupt control registers remain in their previous states. All pins become input or
output port pins or interrupt request pins depending on the settings of P6DDR and the IRQ enable
register. Output pins output the values in P6DR. The MOS pull-ups of input pins are on or off
depending on the values in P6DR.
