4.13 Internal MII Registers Acess and Control
The MTD516 support 2 serial pins (SDIO/SDC) for internal registers acess and control; The detailed
registers informations are presented in Section5.0 (Internal MII Registers).
4.14 LED Display
The MTD516 use 2 pins to output 2 kinds of LED display -- LEDDATA, LEDCLK,
Using LEDCLK rising edge with 32 bits shift register to latch LEDDATA as DATA[31:0]. DATA[15:0]
report Port15~0 link/receive activity led status. DATA[29:16] report packet buffer utilization rating, and
DATA[31] report external memory test result(after power reset, MTD516 will test external SDRAM auto-
matically), DATA[30] report the buffer almost full alarm signal .
