This register is associated with external bus control signals and interrupt
inputs, including data bus enable (DBE), mode select (MODB/IPIPE1,
MODA/IPIPE0), ECLK, size (LSTRB), read/write (R/W), IRQ, and XIRQ.
When the associated pin is not used for one of these specific functions,
the pin can be used as general-purpose I/O. The port E assignment
register (PEAR) selects the function of each pin. DDRE determines the
primary direction of each port E pin when configured to be general-
purpose I/O.
Some of these pins have software selectable pull-ups (DBE, LSTRB,
R/W, IRQ, and XIRQ). A single control bit enables the pull-ups for all
these pins which are configured as inputs.
This register is not in the map in peripheral mode or expanded modes
when the EME bit is set.
Read and write anytime.
This register determines the primary direction for each port E pin
configured as general-purpose I/O.
