Soft power saving

If PS is at logic low level; the chip is forced to shut down all power. If PS is at logic high

level, the chip will be controlled by the SPS bit(the R15 bit of the register) to perform

normally(SPS=Low) or to softly power off the IC(SPS=High). It is recommended to keep PS

at low level (PS = L) while the chip is in no operation mode to save power for all

applications.

D[9:0]:

The level of sink current through pin SINK is set by D[9:0].
