21.3.17 Interrupt Status Register 1 (INTSTS1)
INTSTS1 is a register that is used to confirm interrupt status.
Interrupt generation can be confirmed simply by referencing one of the registers: INTSTS0 when
the function controller function is selected and INTSTS1 when the host controller function is
selected.
The various interrupts indicated by the bits in this register should be enabled only when the host
controller function is selected.
This register is initialized by a power-on reset.
