Glitches and temporary floating inputs can occur if the control bits
regarding each port I/O pin are not performed in the correct sequence.

Do not use read-modify-write instructions on pulldown register A
or B.
Avoid glitches on port pins by writing to the port data register
before changing data direction register bits from a logic 0 to a
logic 1.
Avoid a floating port input by clearing its pulldown register bit
before changing its data direction register bit from a logic 1 to a
logic 0.
The SWPDI bit in the MOR turns off all port pulldown devices and
disables software control of the pulldown devices. Reset has no
effect on the pulldown devices when the SWPDI bit is set.
Two or more output pins of the same port can be connected
electrically to provide output currents up to the sum of the
maximum specified drive currents as defined in
