SROM Download
This function is used to load
the Agilent-supplied firmware
file contents into the ADNS-
3080. The firmware file is an
ASCII text file with each 2-
character byte (hexadecimal
representation) on a single
line.
This mode is activated by the
following steps:
1. Perform hardware reset by
toggling the RESET pin
2. Write 0x44 to register 0x20
3. Write 0x07 to register 0x23
4. Write 0x88 to register 0x24
5. Wait at least 1 frame period
6. Write 0x18 to register 0x14
(SROM_Enable register)
Figure 23. SROM download burst mode
7. Begin burst mode write of
data file to register 0x60
(SROM_Load register)
After the first data byte is
complete, the SROM or micro-
controller must write
subsequent bytes by presenting
the data on the MOSI line and
driving SCLK at the normal
rate. A delay of at least t
LOAD
must exist between data bytes
as shown. After the download
is complete, the micro-
controller must raise the NCS
line for at least t
BEXIT
to
terminate burst mode. The
serial port is not available for
use until it is reset with NCS,
even for a second burst
transmission.
Agilent recommends reading
the SROM_ID register to verify
that the download was
successful. In addition, a
self-test may be executed,
which performs a CRC on the
SROM contents and reports the
results in a register. The test
is initiated by writing a
particular value to the
SROM_Enable register; the
result is placed in the
Data_Out register. See those
register descriptions for more
details.
Agilent provides the data file
for download; the file size is
1986 data bytes. The chip
will ignore any additional
bytes written to the
SROM_Load register after the
SROM file.
SROM file is now available for
download at Agilent’s website.
