Dual MII configuration pin.
LED indicator 2. Strap option: Aging setup. See “Aging” section
PU (default) = aging enable; PD = aging disable.
LED indicator 1. Strap option: PU (default): enable PHY MII I/F. PD: tristate all PHY
MII output. See “Pin 86 SCONF1.”
Serial bus configuration pin.
For this case, if the EEPROM is not present, the KS8995MA will start
itself with the PS[1:0] = 00 default register values .
