Hello John Wieners, one of our engineers, just found a typo in MC56F835x.h (a list of register address #defines) in the directory : C:\Program Files\Metrowerks\CW6\Stationery\DSP56800x_Examples\MC56F8357\isr_led and presumably in other .h files. This is in CW 6.0.1. The .h file doesn't allow for the fact that SCIx_BASE+2 is reserved, at least for the 56F8357. SCI1 has the same error as SCI2. wrong: // Serial Communications Interface 0 (SCI0) #define SCI0_BASE 0x00F280 #define SCI0_BR (SCI0_BASE + 0) #define SCI0_CR (SCI0_BASE + 1) #define SCI0_SR (SCI0_BASE + 2) // <-- should be + 3 #define SCI0_DR (SCI0_BASE + 3) // <-- should be + 4 Rick Corey Senior Software Engineer DPC Instrument Systems Division

Hi Rick and All, It looks like they may have mixed up the 5683xx SCI stuff with the 56F80x SCI stuff. I had just downloaded the latest 56F80x User's Manual and it shows the SCISR and SCIDR as Base + $3 and $4 respectively when it should be Base + $2 and $3.
