Port E Data Direction—
This register controls the data direction of pins 7 through 2.
The external bus function controls the data direction for the associated pins. In this case the data direction bits will
not change.
When operating a pin as a general purpose I/O, the associated data direction bit determines whether it is an input
or output.
1 Associated pin is configured as output.
0 Associated pin is configured as high-impedance input.
Reserved—
Port E bit 1 (associated with IRQ) and bit 0 (associated with XIRQ) cannot be configured as outputs. Port E, bits 1
and 0, can be read regardless of whether the alternate interrupt function is enabled.
