求翻译：若DSP给DDS芯片分配地址为400000H-7FFFFFH，在硬件上将DSP的PAGE1管脚作为DDS芯片的片选，分时产生2MHz和400KHz的电磁波，可通过软件实现。是什么意思？

If the DDS chip DSP to allocate address 400000H-7FFFFFH, the DSP hardware will PAGE1 pin as a DDS chip selection, time-2MHz and 400KHz generate electromagnetic waves, can be realized by software.

If DSP DDS chip to assign addresses to 400,000 FFFFFH H -7, in the hardware, the PAGE DSP DDS 1pin as a chip of the selected films,-produced when the electromagnetic wave 2 MHz KHz and 400, can be achieved through the software.

If DSP for the DDS chip assignment address is 400000H-7FFFFFH, in the hardware General DSP PAGE1 base pin as DDS chip selecting patches or strips of land as worth saving for seed, time sharing produces 2MHz and the 400KHz electromagnetic wave, may through the software realization.

If the DSP assigns addresses to DDS chip is 400000H-7FFFFFH, on the hardware DSP PAGE1 PIN for DDS chip chip select, timesharing and 2MHz of the electromagnetic wave, may be achieved through software.

If DSP assigns the address to be 400000H-7FFFFFH for DDS chip, regards PAGE1 of DSP is in charge of the foot as the chip selection of DDS chip on the hardware, the timesharing produces the electromagnetic waves of 2MHz and 400KHz, can realize through software.
