Error detection and recovery
1. The ADNS-3080 and the
micro-controller might get
out of synchronization due
to ESD events, power supply
droops or micro-controller
firmware flaws. In such a
case, the micro-controller
should pulse NCS high for
at least 1 ms. The ADNS-
3080 will reset the serial
port (but not the control
registers) and will be
prepared for the beginning
of a new transmission after
the normal transaction
delay.
2. Invalid addresses: Writing
to an invalid address will
have no effect. Reading from
an invalid address will
return all zeros.
3. Termination of a
transmission by the micro-
controller may sometimes be
required (for example, due
to a USB suspend interrupt
during a read operation).
To accomplish this the
micro-controller should raise
NCS. The ADNS-3080 will
not write to any register
and will reset the serial port
(but not the control
registers) and be prepared
for the beginning of future
transmissions after NCS goes
low. The normal delays
between reads or writes
(t
SWW
, t
swr
, t
SRAD
, t
SRAD-mot
)
are still required after
aborted transmissions.
4. The micro-controller can
verify success of write
operations by issuing a read
command to the same
address and comparing
written data to read data.
5. The micro-controller can
verify the synchronization of
the serial port by
periodically reading the
product ID and inverse
product ID registers.
6. The microcontroller can read
the SROM_ID register to
verify that the sensor is
running downloaded SROM
code. ESD or similar noise
events may cause the sensor
to revert to native ROM
execution. If this should
happen, pulse RESET and
reload the SROM
instructions.
