Procedure to start motion burst:
1. Lower NCS
2. Send 0x50 to Motion_Burst register.
3. Wait for one frame. (This only applicable in Run mode
4. Start reading SPI Data continuously up to 14bytes.
5. To read new motion burst data, repeating from step 1.
6. Write any value to Motion register (address 0x02) to
Motion burst reporting:
Note: In rest mode, motion burst data is always available or in other
words, motion burst data can be read from Motion_Burst register even
in rest modes.

Motion burst may be terminated by pulling NCS high
for at least t
clear any residual motion.

SROM Download
This function is used to load the Avago supplied firmware
file contents into the ADNS-9500 after sensor power up
sequence. The firmware file is an ASCII text file. There are
2 methods of SROM downloading in ADNS-9500:1.5K and
3K bytes. 1.5K SROM download will only download 1.5K
bytes data into the first half of SROM and leave the rest
empty, while 3K SROM download will download the full
3K bytes data into SROM. They can be selected through
Configuration_IV register, where default setting is 1.5K
SROM download. In the current version of ADNS-9500
sensor, 3K bytes of SROM will be used.
SROM download procedure:
1. Select the 3K bytes SROM size at Configuration_IV
2. Write 0x1d to SROM_Enable register for initializing
3. Wait for one frame
4. Write 0x18 to SROM_Enable register again to start
5. Write SROM file into SROM_Load_Burst register, 1
register, address 0x39
SROM downloading
must start with SROM_Load_Burst register address. All
the SROM data must be downloaded before SROM
start running.
