45 | \ Some hooks for multitasking | |
46 | \ Main task points to the initial task. This usage is currently not ROM-able | |
47 | \ since the user area address has to be later stored in the parameter field | |
48 | \ of main-task. It could be made ROM-able by allocating the user area | |
49 | \ at a fixed location and storing that address in main-task at compile time. | |
