• Manufacturer Part Number: MPS-301A
• Description: Integrated, Absolute Pressure Sensor
• Manufacturer: World Products, Inc.

Note 1: Data must be sampled on the rising edge of the SCK
Note 2: There will be a dummy pulse starting from the middle of the 7
Note 3: At the end of the transfer (24 clocks) the SS must be reasserted (brought high then low again) to begin
