目的：其主要作用是用于调试跟踪和测试
主要包含：MT_TASK、MT_ZDO_FUNC and other MT compile options
LCD_SUPPORTED、LCD_SUPPORTED=DEBUG、BLINK_LEDS
且看正文逐一讲解；
MT_TASK
This compileoption enables the device to be able to talk to the Z-Tool PC application, andto be able to output minimal debug informationusing the debug_str() function. Removing this saves some code and RAM usage.
看点：作用，调用的函数
注意事项：会增大代码量和RAM空间的大小，这对于8位机来说要谨慎，尤其是对于协议栈这样比较大的东西。
MT_ZDO_FUNC and other MTcompile options
MT_ZDO_FUNC is an example of acompile option that enables the ZDO
commands to be used with Z-Tool. Most devices wouldnot need all of
the monitor test commands to beenabled. Each ZDO command can be
enabled individuallyin ZDConfig.h. Selectivelyenabling requests that
need to be in the application minimizes code usa
