Despite the name, when the ISPU is in "sleep" state, it is fully off. In this state, the current consumption is in the order of a few microamperes. In order to keep the ISPU fully in this state you can either set the CLK_DIS bit to 1 in the

ISPU_CONFIG register to completely disable the clock or set the ISPU IRQ rate to 0 Hz by writing ISPU_RATE_[3:0] in the CTRL9_C register to 0h.
