If the device fetches or accesses external memory
while EBDIS = 1, the pins will switch to external bus. If
the EBDIS bit is set by a program executing from exter-
nal memory, the action of setting the bit will be delayed
until the program branches into the internal memory. At
that time, the pins will change from external bus to I/O
ports.

When the device is executing out of internal memory
(with EBDIS = 0) in Microprocessor with Boot Block
mode or Extended Microcontroller mode, the control sig-
nals will be in inactive. They will go to a state where the
AD<15:0>, A<19:16> are tri-state; the OE, WRH, WRL,
UB and LB signals are ‘1’; and ALE and BA0 are ‘0’.
