SNLS582C June 2017 – September 2020 FPC402
PRODUCTION DATA
Writing data to an FPC402 device or the downstream ports under its management requires one SPI transactions. Multiple write transactions to downstream ports can proceed with minimal delay provided that different ports are being written to. If attempting to write data to the same downstream port, then the corresponding downstream access delay, tOFF-SSN, is required. Figure 8-12 shows an example of writing to all four downstream ports in succession.
