Figure 18. Read Operation
Write Operation
Write operation, defined as data going from the micro-
controller to the ADNS-6000, is always initiated by the
micro-controller and consists of two bytes. The first byte
contains the address (seven bits) and has a “1” as its MSB
to indicate data direction. The second byte contains
the data. The ADNS-6000 reads MOSI on rising edges of
SCLK.

Read Operation
A read operation, defined as data going from the ADNS-
6000 to the micro-controller, is always initiated by the
micro-controller and consists of two bytes. The first byte
contains the address, is sent by the micro-controller over
MOSI, and has a “0” as its MSB to indicate data direction.
The second byte contains the data and is driven by the
ADNS-6000 over MISO. The sensor outputs MISO bits on
falling edges of SCLK and samples MOSI bits on every
rising edge of SCLK.
NOTE: The 250 ns minimum high state of SCLK is also the
minimum MISO data hold time of the ADNS-6000. Since
the falling edge of SCLK is actually the start of the next
read or write command, the ADNS-6000 will hold the
state of data on MISO until the falling edge of SCLK.
