Read Operation
A read operation, defined as data going from the ADNS-
5020-EN 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- con-
troller over SDIO, and has a “0” as its MSB to indicate
data direction. The second byte contains the data and
is driven by the ADNS-5020-EN over SDIO. The sensor
outputs SDIO bits on falling edges of SCLK and samples
SDIO bits on every rising edge of SCLK.

ADNS-5020-EN to Microcontroller Handoff
NOTE:
The 0.5/f
SCLK
minimum high state of SCLK is also the
minimum SDIO data hold time of the ADNS-5020-EN. Since
the falling edge of SCLK is actually the start of the next
read or write command, the ADNS-5020-EN will hold the
state of data on SDIO until the falling edge of SCLK.
