13.1.4 Link / Phy Interrupt Enable (LNKPHYINTE) – Base Address: 0x00C
This register is a mirror of the Link/Phy Interrupt Acknowledge (LNKPHYINTACK) register. Enabling an interrupt is accomplished by writing a ‘1’
to the bit corresponding to the interrupt desired.
This register enables the interrupts described in the Link /Phy Interrupt Acknowledge register (LNKPHYINTACK) description. A one in any of the
bits enables that function to create an interrupt. A zero disables the interrupt, however the status is readable in the Link /Phy Interrupt
Acknowledge register.

Bits 21..0 are interrupt enable bits for the Link/Phy Interrupt Acknowledge (LNKPHYINTACK).

13.1.5 Cycle Timer Register (CYCTM) – Base Address: 0x010
Cycle Timer Register operation is controlled by the Cycle Timer Enable (CYTMREN) bit in the Link Control Register (LNKCTL, 0x004). If the
Cycle Timer Register is disabled, it can be used as a general read write register for Host Interface Firmware testing.
