// The maximum number of active objects in QP can be increased to 63,

// active objects cannot exceed the number of embOS thread priorities,

|

// NOTE2:
|
|
// The embOS critical section does not use the status variable, because the

// implementation uses a global up-down counter, which allows the embOS

|
// critical section to nest. Nesting of critical sections is needed in this
|
|
// QP-embOS port.
|
|
//
|
|
// NOTE3:
|
|
// embOS provides only global scheduler locking for all thread priorities
|
|
// by means of OS_EnterRegion() and OS_LeaveRegion(). Therefore, locking the
|
|
// scheduler only up to the specified lock priority is not supported.
