These registers are available

Interrupt Enable Register

The Interrupt Enable Register enables TPI and transmitter to generate interrupts to the host. Hot plug

interrupts to the host are generated even in the D3 (low-power) state. Writing any bit to

enables the

interrupt source, and also clears any pending interrupts. Writing

to disable the interrupt does not

clear any previously pending interrupt.

Interrupt Status Register

The Interrupt Status Register shows current status of interrupt events, even if the event has been

disabled. This register can be polled for activity if the associated interrupt has been disabled. Write 1

to interrupt bits to clear the pending status. Bits 3 and 2 (bits 3:0 on Mobile HD Link devices) serve

only to show the current state and cannot be cleared.
