In DSP2802x_Examples.h the target device chosen in DSP2802x_Device.h also
specifies the maximum SYSCLKOUT frequency (60 MHz or 40 MHz) by setting it to 1
and the other to 0 via compiler directives. This value is used by those examples with
timing dependent code (i.e. baud rates or other timing parameters) to determine
whether 60MHz code or 40MHz code should be run.
The default value is for 60Mhz SYSCLKOUT for the ‘28027 device. If you have
selected a 40 MHz device in DSP2802x_Device.h, the frequency settings are adjusted
accordingly. If you intend to run examples which use these definitions at a different
frequency, then the timing parameters in those examples must be directly modified
accordingly regardless of the setting here.
