Long Address Register Interface
4.3.1
READING LONG ADDRESS
REGISTERS
The long address space is accessed by sending a ‘
1
as the first bit of the SPI transfer. The following 10 bits
are the address of the target register. The final bit is a
0
‘ to indicate that the command is a read. On the next
clock edge of SCK, the Most Significant bit of the
register will shift out, followed by the rest of the bits.
