* NOTE01:
* The maximum number of active objects QF_MAX_ACTIVE could be increased to
* 63 inclusive. Here, the lower limit is used only to save some RAM.
*
* NOTE02:
* The QF_CRIT_STAT_TYPE macro is defined, which means that this QP port
* uses the policy of "saving and restoring critical section status". This
* policy allows nesting of critical sections.
*
* The TMS320C28x automatically disables interrupts upon the entry to an ISR
* by setting the INTM mask. This means that the whole body of an ISR is a
* critical section. Therefore, in order to call QP services from ISRs, this
* port uses policy that allows nesting critical sections.
