DESCRIPTION
0.15
RESET
R, W, 0, SC
GLOBAL: Works for both HPNAEN=0,1
RESET: Setting this bit to logic one resets the entire 2132. This bit is
self clearing.
GLOBAL: Works for both HPNAEN=0,1
LOOPBACK: When this bit is set, no transmission of data on the
network medium occurs and any receive data on the network
medium is ignored. The internal loopback signal path encompasses
the 2132 digital core and most of the analog circuitry.

ANEGEN
R, (0)
HPNAEN=0 ANEGEN =0 enable FD/HD
HPNAEN=1 ANEGEN=0 1M8
AUTO-NEGOTIATION ENABLE: The 2132 supports auto-negotiation
for FDX/HDX in 10baseT mode. The default value of this bit is set by
the ANEGA pin.
0.11
PWRDN
R, W, 0
GLOBAL: Works for both HPNAEN=0,1
POWER-DOWN: The 78Q2132 may be placed in a low power
consumption state by setting this bit to logic one. While in
power-down state, the 78Q2132 still responds to management
transactions. The power-down state can also be achieved by setting
PWRDN pin high.
GLOBAL: Works for both HPNAEN=0,1
ISOLATE: When set, the 78Q2132 will present a high impedance on
its MII output pins. This allows for multiple PHYs to be attached to
the same MII interface. When the 78Q2132 is isolated, it stills
responds to management transactions. The default value of this bit
depends on the ISODEF pin. When ISODEF pin is tied high the ISO
bit defaults to high. When ISODEF pin is tied low, the ISO bit
defaults to low. The same high impedance state can be achieved
through the ISO pin.

HPNAEN=0 RESTART AUTO-NEGOTIATION: If auto-negotiation is
enabled, setting this bit re-starts the auto-negotiation process. This
bit is self-clearing.
