for my project I'm trying to utilize the register to better control the mcan module how i need and i see this PSR ACT portion give me part of what I'm looking to do, but it doesn't seem to work as stated in the Manuel. when testing I'm not seeing ACT change and always indicates idle. how is the ACT portion of the PSR suppose to work?
Hi,
As the name of PSR implies, the ACT bits reflect the state of CAN bus, if you want to see if the ACT bits change or not based on CAN bus action, you can have a test.
You can modify the code like the attached code. I use the example for LPC5506 instead of LPC5516.
Hope it can help you

in the end still didn't see any actions from the ACT portion ended up just following the IR and IE register as a status of the module.
