Selection of Pin Functions
The function depends on the interrupt request 3 enable bit (IRQ3E) and P6PWME
bit in SYSCR2, and the OE bit of PWM timer 1.

When used for P60 input/output, the input or output function is selected by P60DDR.
9.7.4 Built-In MOS Pull-Up
Port 6 has programmable MOS input pull-ups which are turned on by clearing the corresponding
bit in P6DDR to 0 and writing a 1 in P6DR. These pull-ups are turned off at a reset and in the
hardware standby mode. Table 9-12 indicates the status of the MOS pull-ups in various modes.

Notation:
OFF:
The MOS pull-up is always off.
ON/OFF: The MOS pull-up is on when P6DDR = 0 and P6DR = 1, and off otherwise.
Note: When P61, P62, and P63 are used for PWM timer output, their MOS pull-ups are switched
off regardless of the values in P6DDR and P6DR.
