XRS(CPU复位引脚,输入) Device Reset (in) and Watchdog Reset (out). Device reset. XRS causes the device to terminate execution. The PC will point to the address contained at the location 0x3FFFC0. When XRS is brought to a high level, execution begins at the location pointed to by the PC. This pin is driven low by the DSP when a watchdog reset occurs. During watchdog reset, the XRS pin will be driven low for the watchdog reset duration of 5
