14.5.10 Read, Write or Jump into RAM

RRAM and WRAM operations perform 16-bit read/write accesses into any RAM area of the system memory. The ADDR[31:0] register must be updated first with the address of in the system memory of the 16-bit word in RAM to be read or written. Then, the ADDR[31:0] register is automatically incremented by 2 after each DATA command within the RRAM or WRAM operation. There is no alignment constraint when accessing the system RAM.

Finally, the JRAM operation makes the FFPI Monitor jump into an address in the system RAM to execute the binary code previously loaded into this address. The binary code is executed after the target device has processed a DATA command within a JRAM operation.
