It is basically to put the task to sleep indefinitely, until something else in the system wakes it up.<BR /><BR />TK_YIELD() is the function to pass control to the next task and come back after once around the task list.<BR /><DIV></DIV></BODY></HTML> Tue, 18 Nov 2008 07:05:44 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/TK-BLOCK-vs-TK-SLEEP/m-p/202720#M9390 daverj 2008-11-18T07:05:44Z
