2.4. UFM Operating Modes
The UFM block offers the following operating modes:
- Read
- Burst read
- Program (Write)
- Sector erase
- Page erase
- Sector write protection
You can choose one of the following access modes in the On-Chip Flash Intel® FPGA IP core parameter editor to read and control the operations.
- Read and program mode—this mode allows both data and control slave interface. This mode is applicable for both UFM and CFM sectors.
- Read only mode—this mode allows only data slave interface, and restricted to only read operations. This mode is applicable for both UFM and CFM sectors.
- Hidden—this mode does not allow any read or program (write) operations. This mode is applicable only for CFM sectors.
The following table shows the comparison between parallel and serial modes.
Feature | Parallel Mode | Serial Mode |
---|---|---|
Avalon-MM Data Interface | Parallel mode with 32-bit data bus | Serial mode with 32 bits based burst count |
