25.15 – interrupt Pin Enable

When bit 25.15 is set to “1”, the hardware interrupt is enabled, meaning that the state of the external interrupt pin (MDiNT) can

be influenced by the state of the interrupt Status bit (26.15). When bit 25.15 is set to “0”, the interrupt status bits (Register 26)

continue to be set in response to interrupts, but the interrupt hardware pin MDiNT on the VSC8221 will not be influenced by this

particular PHY.

25.14 – Reserved

25.13 – Link State-Change interrupt Mask

When bit 25.13 is set to “1”, the Link State-Change / Energy Detect interrupt is enabled.

25.12 – Reserved

25.11 – Auto-Negotiation Error interrupt Mask

When bit 25.11 is set to “1”, the Auto-Negotiation Error interrupt is enabled.

25.10 – Auto-Negotiation-Done / interlock Done interrupt Mask

When bit 25.10 is set to “1”, the Auto-Negotiation-Done interrupt is enabled.

25.9 – inline Powered Device Detected interrupt Mask

When bit 25.9 is set to “1”, the inline Powered Device Detected interrupt is enabled.

25.8 – Symbol Error interrupt Mask

When bit 25.8 is set to “1”, the Symbol Error interrupt is enabled.

25.7 – Descrambler Lock-Lost interrupt Mask

When bit 25.7 is set to “1”, the Descrambler Lock-Lost interrupt is enabled.

25.6 – TX FiFO interrupt Mask

When bit 25.6 is set to “1”, the TX FiFO interrupt is enabled.
