Output
Input/Output
Chip Select 1 (CS1)
—When enabled, a CSx signal is asserted for
external memory accesses that fall within a programmable address
range.
Port A GPIO (1)
—A general purpose IO pin.

Chip Select 2 (CS2)
—When enabled, a CSx signal is asserted for
external memory accesses that fall within a programmable address
range.
Port A GPIO (2)
—A general purpose IO pin.

Data Bus
(D0–D12)
—specify the data for external program or data
memory accesses. D0–D15 are tri-stated when the external bus is inactive.

/Output
Data Bus (D13–D15)
— specify the data for external program or data
memory accesses. D0–D15 are tri-stated when the external bus is inactive.
Mode Select
—During the bootstrap process the MODE A, MODE B,
and MODE C pins select one of the eight bootstrap modes. These pins
are sampled at the end of reset.
Note:
Any time POR and EXTERNAL resets are active, the state of
MODE A, B and C pins get asynchronously transferred to the SIM
Control Register [14:12] ($1FFF08) respectively. These bits determine
the mode in which the part will boot up.
Note:
Software and COP resets do not update the SIM Control
Register.

RD
Output
Bus Control– Read Enable (RD)
—is asserted during external memory
read cycles. When RD is asserted low, pins D0–D15 become inputs
and an external device is enabled onto the data bus. When RD is
deasserted high, the external data is latched inside the controller. RD
can be connected directly to the OE pin of a Static RAM or ROM.
