w INTRODUCTION WAN-0143 ADA and MASK Timing on WM9712 This applications note has been created to detail the timing of the MASK and ADA (ADC Data Available) signals on the WM9712 device. This applications note should be used in conjunction with the latest WM9712 datasheet. The WM9712 has many additional functions to aid the design of portable applications. Pin 47 of the device can be configured for either MASK input, ADA output or standard GPIO functionality. The MASK function can be used to pause and control auxiliary ADC conversions. The ADA function can be used to indicate when data becomes available from the auxiliary ADC. The timing associated with both signals is detailed in the following sections of this document.
