(1)
Selects the type of interface. A
logic 1 selects the Motorola
MPC860 mode; a logic 0 selects
the Mindspeed EBUS mode.
Microprocessor interface clock.
Frequencies may range from
8 to 33 MHz.
Microprocessor read/write control
when the Motorola MPC860 mode
is selected via the MMode pin.
Microprocessor write control
when operating in the Mindspeed
EBUS mode
Microprocessor read control
when operating in the Mindspeed
EBUS mode.
Microprocess transfer start when
operating in the Motorola
MPC860 mode. Microprocessor
address latch when operating in
the Mindspeed EBUS mode.
When MCS* is set to a logic “0,”
the device is enabled for read and
write accesses. When MCS* is set
to a logic “1,” the device does not
respond to input signal transitions
on MClk, MRW*, MRD*, MTS*.
Additionally, when MCS* is set to
a logic “1,” the MAD[7:0] pins are
in a high-impedance state but the
MIntr* pin remains operational.
Address inputs for identifying the
register that will be accessed.
Mindspeed EBUS mode, only pins
[10:8] are used for the address
and pins [7:0] are unused. The
lower 8 bits of the EBUS address
are multiplexed on the micro
interface data bus (MAD). See
Figures 5-5
When operating in the

and 5-6.
