WRITING SHORT ADDRESS
REGISTERS
The short address space is accessed by sending a ‘
0
as the first bit of the SPI transfer. The following 6 bits
are the address of the target register. The final bit of the
first byte is a ‘
1
’ to indicate that the command is a write.
On the next clock edge of SCK, the Most Significant bit
of the register will shift out, followed by the rest of the
bits.
