CrystalLAN™ 100BASE-X and 10BASE-T Transceiver

DCR Rollover

Read/Write 0

When set, an interrupt will be generated if the MSB in

the DCR counter becomes set.

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.

FCCR Rollover

Read/Write 0

When set, an interrupt will be generated if the MSB in

the FCCR counter becomes set.

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.

RECR Rollover

Read/Write 0

When set, an interrupt will be generated if the MSB in

the RECR counter becomes set.

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.

Remote Loopback

Fault

Read/Write 0

When set, an interrupt will be generated if the elastic

buffer in the PMA is under-run or over-run during

Remote Loopback. This should not occur for normal

length 802.3 frames.

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.

Reset Complete

Read/Write 1

When set, an interrupt will be generated once the

digital and analog sections have been reset, and a

calibration cycle has been performed.

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.

Jabber Detect

Read/Write 0

When set, an interrupt will be generated when a Jab-

ber condition is detected by the 10BASE-T MAU.

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.
