11 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.

10 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.

9 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.

8 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.

7 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.

6 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.
