Microprocessor interface clock.
Selects the type of interface. A
logic 1 selects the Motorola
MPC860 mode; a logic 0 selects
the Mindspeed EBUS mode.
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
and 5-6.
