Recommended Actions
Before Setting Next
Power Mode
Stop DSP by setting
Run[15:0] = 0x0000.
Disable HSDC by clearing
Bit 6 (HSDEN) to 0 in the
CONFIG[15:0] register.
Mask interrupts by setting
MASK0[31:0] = 0x0 and
MASK1[31:0] = 0x0.
Erase interrupt status flags in
the STATUS0[31:0] and
STATUS1[31:0] registers.

PSM1
Current mean absolute
values (mav) computed
immediately.
xIMAV[19:0] registers may
be accessed immediately.
Wait until the IRQ1 pin
triggered low.
Current mean absolute
values are computed
beginning this moment.
xIMAV[19:0] registers may
be accessed from this
moment.
Wait until the IRQ1 pin is
triggered low.
Current mav circuit begins
computations at this time.
xIMAV[19:0] registers can
be accessed from this
moment.
