Notes
From PD (when bit 1 of register 0x0d
is set) to low current
From PD inactive (when NRESET pin is
asserted high or write 0x5a to register
0x3a) to valid motion
Active low.
From NRESET pull high to valid mo
tion, assuming V
DD
and motion is
present.

Data held until next falling SCLK edge.
From data valid to SCLK rising edge.
From rising SCLK for last bit of the first
data byte, to rising SCLK for last bit of
the second data byte.
From rising SCLK for last bit of the first
data byte, to rising SCLK for last bit of
the second address byte.
From rising SCLK for last bit of the first
data byte, to falling SCLK for the first
