Description
External Bus Release Enable
Enables/disables external bus release.
0: External bus release disabled
1: External bus release enabled*
For details, see section 13, I/O Ports.
BREQO Pin Enable
Controls outputting the bus request signal (BREQO)
to the external bus master in the external bus
released state when an internal bus master performs
an external address space access.
0: BREQO output disabled
1: BREQO output enabled
