eDMA
|
||
|
|
----
|
||
|
|
|
||
|
|
Enhanced Direct Memory Access module. There is a driver that was copied from the S32K1XX and i.MX RT ports. Some modifications have been made to make it work with S32K3XX, but it is far from feature-complete.

||
|
|
|
||
|
|
eMIOS
|
||
|
|
-----
|
||
|
|
|
||
|
|
The Enhanced Modular IO Subsystem (eMIOS) is a flexible timer and I/O module for real-time control applications. Its channels can be used for (pulse) counters, PWM outputs, input period measurements, and more. There is no driver implementation available (yet).
