ADAU1467 External control single slew volume control slew rates
What are the slew rates for this block please? I've found a thread on the similar device on the ADAU145x, but that seems to have values from 0.....41 whereas on the 1467 it's 0....15.

Hello dunmail,
The External control single slew algorithm and all the other algorithms will work in the same way whether it's ADAU145x or ADAU146x processors. The major differences between the ADAU145x and ADAU146x series are the memory unit (program memory and data memory) and extra pins like SDATAIO pins(only for ADAU1463/66), GPIO pins, Auxadc pins, clock frequency(only ADAU1450 runs at 147.5MHZ) and few. So you really do not need to bother about the algorithm parts between 145x and 146x processors unless you have memory concern.
For this External control single slew module, you will have four slew types .The slew values for linear slew is 0 to 15, for exponential and RC slew it is 0 to 63 , for constant time slew it is 0 to 7. You will be able to change it by clicking the blue color slew icon on the module. Kindly refer the attached document for Hardware slew types.
Kindly reply if you need any clarification.

Harish
