Logic

External Bus

XA[23:19]

O

Address bus to external RAM, external ROM, external I/O banks, and

external DRAM. After a reset, these pins are configured for their primary

function (PIOA[14:10]).

XWR

O

Data transfer direction for external bus, used when connecting to Motorola

I/O devices. This represents the secondary function of pin PIOA[15],

produced by setting bit 7 in the port control (GPCTL) register to "1."

Secondary

—

XWAIT

I

External I/O bank 0 WAIT signal.

This input permits access to devices slower than register settings.
