High-performance Optical Mouse Sensor

HP => Agilent Technologies 

Write Operation

Write operation, defined as

data going from the micro-

controller to the ADNS-3060,

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-3060 reads MOSI on

rising edges of SCLK.

Read Operation

A read operation, defined as

data going from the ADNS-

3060 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-

3060 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-3060. Since

the falling edge of SCLK is actually the

start of the next read or write

command, the ADNS-3060 will hold

the state of data on MISO until the

falling edge of SCLK.
