What is the expected maximum slew rate if DEFSLEW is set to “immediate”? Customer is trying to get the voltage scaling as quick as possible (they use DEFDCDC3 to change between 2 voltages). Customer would like to know how long they have to wait from an OMAP3 perspective before they can assume that the voltage has been stable after a change. So far they have it set for DEFSLEW=7.2mV/us, but they would like to know if “immediate” is faster and how much faster.
Setting DEFSLEW to immidiate will result in approx 10mV/us slew rate.
Originally there was a GO bit that needed to be set to start voltage change. The option immidiate did not need the this GO bit to be set.
This function was removed, so all slew rate option start voltage change with end of I2C transmission.
