• Manufacturer Part Number: cp3cn23
• Description: Cp3cn23 Reprogrammable Connectivity Processor With Dual Can Interfaces
• Manufacturer: National Semiconductor Corporation

Note 1: The ENV0, ENV1, ENV2, RESET, TCK, TDI, and TMS pins each have a weak pull-up to keep the input from floating.
Note 2: These functions are always enabled, due to the direct low-impedance path to these pins.
