Multipurpose I/O Bank 0 Enable
These bits control the output enables on the I/O pins
MPIO0_0, MPIO0_1, MPIO0_2, MPIO0_3, MPIO0_4,
MPIO0_5, MPIO0_6, and MPIO0_7. A value of 1 turns on
the pin driver, and a value of 0 3-states the pin. Because
the value in this register powers up to all zeros, the pins
will initially be 3-stated at power-up. These pins also have
internal 100 µ A pull-down resistors, which can be
disabled with the
