Configuration

MFPs are divided into speed groups by digital function. The slew rate adjustment register configures the rise and
fall times for each MFP in the group simultaneously. The MFP slew rate can be adjusted at any time, and the
changes are applied immediately.
The MFP slew rate configuration applies to all pins in the speed group regardless of the enabled function of the pin.
For example, the speed setting is applied to a GPIO and a dedicated pin function if both are in the same MFP speed
group.
Refer to the corresponding device's data sheet "Control- and Side-Channel Typical Rise and Fall Times" section for
V timing details. The table below represents slew rate registers and the typical rise and fall times.

Audio

Overview

I S or TDM is available on GMSL devices. Typical use case is to send audio data from one end to the other via the

GMSL link. GMSL2 devices support bidirectional transmission of audio (i.e., I
channels of the serial link.
