Write Operation
Write operation, defined as data going from the micro-
controller to the ADNS-6030, 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-6030 reads MOSI on rising edges
of SCLK.
Read Operation
A read operation, defined as data going from the ADNS-
6030 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-6030 over MISO. The sensor outputs MISO bits on
falling edges of SCLK and samples MOSI bits on every
rising edge of SCLK.
Note: The 0.5/fSCLK minimums high state of SCLK is also the minimum
MISO data hold time of the ADNS-6030. Since the falling edge of SCLK
is actually the start of the next read or write command, the ADNS-6030
will hold the state of data on MISO until the falling edge of SCLK.
