The RTX51 Tiny "tips" article states the following:
Round-robin multitasking is preemptive. It interrupts your task and switches to a new task after the specified number of OS ticks. Refer to CONF_TNY.A51.
But elsewhere in the documentation (http://www.keil.com/support/man/docs/tr51/tr51_sysreq.htm, among others), it is stated that Tiny can only do cooperative (not preemptive) multitasking. Why the discrepancy?
Also: task priorities can not be assigned in RTX-Tiny (as per the above referenced article). So why does the option to disable round-robin task switching (in conf_tiny_banking.a51) exist if round-robin is the only allowed method anyway? In other words, will the system act any differently whether or not RR is disabled?
