Hi Does anyone happen to know whether the C compiler for 5680x (either version 5.0.4 or 5.1) passes structs as pointers, or by value? I mean, does it put every byte of the struct onto the stack, or just pass a reference? For instance, would this invocation

In my product I need to store unvolatile data when the power supply goes down. Internal flash memory seem be right for this. The problem is that I not know the maximun programming time of internal flash. Does anyone have an idea on this time ? It seems difficult to obtain!!

Has anybody had experience with apparent hardware failure localised to JTAG functions on 5680x's ? We had 3 NewMicros boards fail yesterday, where symptom of failure is no connection to board from CodeWarrior, however at least 1 of the boards during the attempted connection/ download

I'm trying to use a quad timer block to capture the period of an encoder input for velocity calculation. The problem I'm having is that the input period is quite small and frequent, so I really don't want to service an interrupt as part of the capture. One problem I'm having i

Hi, in manual there is written following about CANTCL1 register bits (ch. 8.8.2 of 5680x User's manual): "These bits are read/write at any time when SFTRES = 1, except CANE. It is write once in normal modes and any time in special modes when SFTRES = 1."
