Function
Port 1 MII Transmit Data bit 0/Chip ID Bit 0
During power on reset, value will be latched by
ADM6993/X at the rising edge of RESETL as
CHIPID_0.This pin will become P1RXD0 if
P1BUSMD[1:0] is 11. Synchronous to the rising edge of
TXCLK.
Port 1 MII Transmit Data bit 1/Chip ID Bit 1
During power on reset, value will be latched by
ADM6993/X at the rising edge of RESETL as
CHIPID_1.This pin will become P1RXD1 if
P1BUSMD[1:0] is 11. Synchronous to the rising edge of
TXCLK.
Port 1 MII Transmit Data bit 2/ Port 1 Bus Mode bit 0
During power on reset, value will be latched by
ADM6993/X at the rising edge of RESETL as
P1BUSMD0.This pin will become P1RXD2 if
P1BUSMD[1:0] is 11. Synchronous to the rising edge of
TXCLK.

Port 1 MII Transmit Data bit 3/ Port 1 Bus Mode bit 1
During power on reset, value will be latched by
ADM6993/X at the rising edge of RESETL as
P1BUSMD1.This pin will become P1RXD3 if
P1BUSMD[1:0] is 11. Synchronous to the rising edge of
TXCLK.
