DESCRIPTION
Next Page
Read/Write 0
When set, this bit enables the ability to exchange
Next-Pages with the link partner. This bit should be
cleared if it is not desired to engage in Next Page
exchange.
Note:
This bit is disabled, and writes to this bit are
ignored when the National Compatibility Mode bit of
the 10BASE-T Configuration Register (address 1Ch)
is set.
When set, this bit indicates consistent reception of
the link partner
s data.
This bit may be used to indicate a fault condition to
the link partner. Setting this bit will signal to the link
partner that a fault condition has occurred.
This field determines the advertised capabilities of
the CS8952 as shown below. When the bit is set, the
corresponding technology will be advertised during
auto-negotiation.
