DEBUG寄存器：word 0xa0000010
word 0xa0000010 1 //debug开
word 0xa0000010 0 //debug关
当然也可以按模块打开/关闭debug信息，如 DBGCFG_KMF/DBGCFG_UMF/DBGCFG_MENU/DBGCFG_TUNER模块等。
所以大家在使用过程中要按源文件所在的模块加打印信息，这样的话，按模块开启或关闭打印信息较为方便。
如在“atv_app.c”中添加打印信息，应该使用“atv_printf()”而不是“printf()”，因为在“atv_app.c”中已经定义了如下关联：
#define atv_printf(fmt, arg...) UMFDBG(0,"[ATV App]" fmt, ##arg)
将“atv_printf”与“UMFDBG”进行了关联，我们设置“word 0xa0000010 0x400”可以单独控制此模块的debug。
不同模块设置的寄存器值是不一样的，如umf debug值为0x400，具体在文件“drv_debug.h”中定义。
