RZ2 zHop contains anomalous data for the first two sample cycles

Tech Note: TN0267
Product: RZ2
Version: Serial numbers < 2000
Date Added: 2007-10-01


Anomalous data values may be generated at the output of zHop components in the first two sample cycles of a newly run process. The initial value on the RZ zHop bus floats high (resulting in a HEX value of FFFF) during inactive cycles and may affect the circuit when the processing chain is executed on the device.


Initial startup delays associated with software applications such as OpenEx may mitigate the effect of this anomaly. If you do experience any issues related to this problem, please contact TDT and request an RMA for an upgrade to eliminate this problem.
