Multipurpose I/O Bank 1 Enable
These bits control the output enables on the I/O pins
MPIO1_0, MPIO1_1, MPIO1_2, MPIO1_3, MPIO1_4,
MPIO1_5, MPIO1_6, and MPIO1_7. A value of 1 turns on
the pin driver, and a value of 0 3-states the pin. Because
this register powers up to all zeros, the pins will initially
be 3-stated at power-up. These pins also have internal
100 A pull-down resistors, which can be disabled with
the
register (0xFF25).
Multipurpose I/O Bank 1 Input
These read only bits read the live input values on the I/O
MPIO1_0, MPIO1_1, MPIO1_2, MPIO1_3, MPIO1_4,
MPIO1_5, MPIO1_6, and MPIO1_7.
