MT9160B/61B
Advance Information
84
Motorola/National operation. Refer to the relative
timing diagrams of Figures 5 and 6.
Receive data is sampled on the rising edge of SCLK
while transmit data is made available concurrent with
the falling edge of SCLK.
Flexible Digital Interface
A serial link is required to transport data between the
MT9160B/61B and an external digital transmission
device. The MT9160B/61B utilizes the ST-BUS
architecture defined by Mitel Semiconductor but also

Delays due to internal processor timing which are transparent.
The MT9160:-latches received data on the rising edge of SCLK.
-outputs transmit data on the falling edge of SCLK.
y
The falling edge of CS indicates that a COMMAND/ADDRESS byte will be transmitted from the microprocessor. The
subsequent byte is always data until terminated via CS returning high.
A new COMMAND/ADDRESS byte may be loaded only by CS cycling high then low again.
The COMMAND/ADDRESS byte contains:
1 bit - Read/Write
3 bits - Addressing Data
4 bits - Unused
