The 88E6352 is configured with P5_MODE=6, S_SEL=1 and S_MODE=1, which means port 5 is configured as 1000BASE-X. This is confirmed by the value in the 88E6352 port 5 status register, 0x4e09, where C_MODE=9 meaning 1000BASE-X. It is also confirmed by the 88E6185 port 9 status register, 0x5e8c, where C_MODE=4 meaning cross-chip SERDES mode is selected.
