When FDB0/FDB1 LUT mode is disabled, then Generic 8KB/16KB broadside RAM mode is enabled. Both memory banks (Bank0 and Bank1) are used in this mode of operation. Either PRU core (PRU0 or PRU1) can access Bank0 or Bank1 via the FDB_Data/FDB_Address. RTU_PRU0 and RTU_PRU1 auxiliary cores only have access to the results of the lookup. The auxiliary cores (RTU_PRU0 and RTU_PRU1) can not write or read to the FDB memory banks.
