• Manufacturer Part Number: FIDO1100PQF208IR1
• Description: 32-bit Real-time Communications Controller
• Manufacturer: Innovasic Semiconductor Inc.

Flexible Input Deterministic Output (fido ® )
32-Bit Real-Time Communications Controller
Errata No. 4
Problem: When using the RDY_N signal to insert wait states (chip select timing register
RDY_ENABLE bit = 1), the Address bus timing is incorrect.
Description: When used in this way, the Address bus will change states coincident with, or in
some cases, before the end of the bus cycle. This can cause data corruption in memory.
Workaround: There is no work around for this problem. It is recommended to avoid use of the
RDY_N signal and the RDY_ENABLE bit of the chip select timing registers.
