AX88796BLF / AX88796BLI
Appendix A4: co-work with 32-bit processor
An example, AX88796B co-work with Samsung 2440 processor. (32-bit processor with external 16-bit bus)
AX88796B’s bus setting as ISA mode. (Without external resister connect to EECS and EECK) Host can use burst
read mode, it is useful host processor increment its address when moving AX88796B received data.
AX88796B supports two kinds of Data Port for receiving/transmitting packets from/to AX88796B. One is the PIO
Data Port (offset 10h); the other one is the SRAM-like Data Port (e.g. offset 800h ~ FFFh for Samsung2440
processor as described in below figure). The SRAM-like Data Port address range depends on which address line of
host processor is being connected to the address line SA5/FIFO_SEL of AX88796B.
Software on host CPU can issue Single Data Read/Write command to both PIO Data Port and SRAM-like Data Port.
However, to use Burst Data Read/Write commands, one has to use SRAM-like Data Port, which requires
SA5/FIFO_SEL (pin 45) of AX88796B connecting to an upper address line of host CPU. AX88796B with Samsung
2440 processor reference schematic has SA5/FIFO_SEL pin connected to upper address line (i.e. A11 of Samsung
2440) for supporting Burst Data Read/Write commands.
