16.9

CMD_LO_SPD

0,RW

Command Low Speed:

1= Transmit speed is set to low

0= Normal operation

Remote commands will be issued if this bit is set

16.8

CMD_HI_SPD

0,RW

Command High Speed:

1= Transmit speed is set to high

0= Normal operation

Remote commands will be issued if this bit is set

16.7

AID_ADR_NEG

0,RW

AID Address Negotiation:

1= Stop AID address negotiation

0= Normal operation

16.6

CLR_NS_EVNT

0,RW

Clear Noise Event Register:

1= Clear the Noise Event Register

0= Normal operation

16.5

SLC_LVL_ADP

0,RW

Slice Level Adaptation:

1= Slice level adaptation is disabled (stopped).

0= Slice level adaptation is enabled

16.4

PWR_DWN

0,RW

Power Down:

Writing a 1 to this bit will cause DM9801A to enter Sleep mode

and power down all circuits except the oscillator and clock

generator circuit. To exit Sleep mode, write 0 to this bit position.

The prior configuration will be retained when the sleep state is

terminated, but the state machine will be reset

16.3

Reserved

0,RW

Reserved:

This bit must be written as 0

16.2

Speed

1, RW

Speed:

1= high speed

0= low speed

This bit indicates the network speed is set to high as selected

by the status of the SPDSEL pin during power-up/reset.

16.1

Power

0, RW

Power:

1= high power

0= low power

This bit indicates the network power is set to high as selected

by the status of the PWRSEL pin during power-up/reset.
