Hi all,I'm trying add FPU exception to my project and I'm bit confused because two sources points two different interrupt vectors for this. Book E says, FPU exception is under IVOR33 but SPC58xH manual points IVOR10. And SPC5Studio libraries have "de...

Hi all,I'm working on SPI communication between SPC582B and peripherals. I succesfully made it but I've found, delay between characters sent by CPU is about 8us in 1MBit mode. Delay between last transmitted bit and tfff (transmit FIFO not full) is a...

Is it necessary switch to hardware vector mode to support FPU exception in IVOR10? regardsMichal

Hi Erwan,I've found bug in application note AN5549 where figures 6 and 10 should be swapped. Hardware vector mode require vector table at offset 0x1000 so fig. 10 is incorrect.regardsMichal

If I remember, CAN in SPC57x (I've used SPC572L) is identical as in SPC58x so I used Application note for 58x. Also, SPC5Studio filter generator for SPC57 does not support all modes, so I created config using one of SPC58 CPUs and copied to SPC57 con...

Hi,it does not work, probably SPC5Studio bug. regards

I've tried DMA but it does not change situation. Space between characters is about 8.5us. Clock generated by master for incoming data also has 8.5us breaks.
