4.4.2 Termination Requirements
Open-drain pins on the CS470xx must be pulled high for proper operation. Please refer to the
CS470xx Hardware User’s Manual
to identify which pins are open-drain and what value of pull-up
resistor is required for proper operation.
Mode select pins on CS470xx are used to select the boot mode upon the rising edge from reset. A
detailed explanation of termination requirements for each communication mode select pin can be
found in the CS470xx Hardware User’s Manual.
4.4.3 Pads
The CS470xx Digital I/Os operate from the 3.3 V supply and are 5 V tolerant.
4.5 Application Code Security
The external program code may be encrypted by the programmer to protect any intellectual
property it may contain. A secret, customer-specific key is used to encrypt the program code that is
to be stored external to the device. Please contact your local Cirrus representative for details.
