System Interfaces

XVF3610 voice processor provides the following additional interfaces to increase usability and reduce total system cost:

• 4 General Purpose Output pins. These can be configured as simple digital I/O pins, Pulse Width Modulated (PWM) outputs and rate adjustable LED flashers.

• 4 General Purpose Input pins. These can be used as simple logic inputs or event capture (edge detection).

• I2C and SPI master to control external devices such as ADCs, DACs or external keyword detection devices.
