I find it amazing the fact that I can't get detailed information of the hcs12, I trying to obtain info that describes the different operation modes, such as hardware configuration for programming and for a normal code run as well as other features and all I find in the freescale website is summarized info, and links to books that claim to have more detailed information. It is funny because I

Dear colleagues, I'd like to use HCS12 in one application, where the user input will be from discrete incremental rotary sensor (in fact, HDD motor with appropriate shaping amplifiers). It gives two logical signals, which are phase shifted (if driven by constant velocity, shift is 90deg.): A: 000011110000111100001111 B: 00111100001111000011110


Waking up from Pseudo-Stop with HCS12

Hi All I have some code where I put the HCS12 chip to sleep in pseudo-stop mode (i.e PSTP = 1, followed by asm STOP). To the best of my understanding all clocks/oscillators are stopped except for OSCCLK, which causes the real-time interrupt to be generated. The RTI is used to wake up the system. I am working with the NE64 chip. Has anyone worked with putting the device to sleep before?

My BDM and/or debugger sometimes sets the HCS12 in secure mode. I suspect that it has something to do with the target clock speed, sence the problem has only (yet) occured when I have the HCS12 to run in self clock mode. This do not happen very often, perhaps once per 50 download
