4.3 DSP I/O Description
4.3.1 Multiplexed Pins
Many of the CS4953xx pins are multi-functional. For details on pin functionality please refer to the CS4953xx
Hardware User’s Manual.
4.3.2 Termination Requirements
Open-drain pins on the CS4953xx must be pulled high for proper operation. Please refer to the CS4953xx
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 the CS4953xx are used to select the boot mode upon the rising edge of reset. A detailed
explanation of termination requirements for each communication mode select pin can be found in the
CS4953xx Hardware User’s Manual.
4.3.3 Pads
The CS4953xx I/O operates from the 3.3 V supply and is 5V tolerant.
4.4 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.
