Appendix 3
The buffer memory is used for the following applications.
Module
RJ71EN71, RnENCPU (network part)
CPU module (built-in Ethernet port
part)
Buffer memory values are reset to default when the CPU module is reset or the system is powered off.

List of buffer memory addresses

RJ71EN71, RnENCPU (network part)
The following table lists the buffer memory addresses of the RJ71EN71 and the RnENCPU (network part) when the network
type is set to "Ethernet".
For the addresses of the RJ71EN71 when the network type is set to "Q Compatible Ethernet", refer to the following.
