Only the 2 MSBs are updated on the rising edge of SLE; other register bits are
unchanged.
•
The address and R/W bits are clocked on the rising edge of SCK.
The data bits are changed on the falling edge of SCK. The MSB of the register is the first
bit read.
SDATA I/O pin is switched from input to output on the edge following the "1" clocking the
R/W bit.
It is possible to stop reading a register (SLE back to “1”) at any time.
If an attempt to read more bits than the register capacity is detected, SDATA is clamped
to “0”.
If the address of a register is not valid, SDATA is set to “1” during the first 32 SCK peri-
ods, then to “0” during all the extra periods.
SDATA is switched back to the input state when SLE is back to “1”.
