Description
Buffer Ready Interrupt Status
Indicates the BRDY interrupt status.
0: BRDY interrupts not generated
1: BRDY interrupts generated
This module sets this bit to 1 when at least one
PIPEBRDY bit in BRDYSTS is set to 1 among the
PIPEBRDY bits corresponding to the PIPEBRDYE
bits in BRDYENB to which 1 has been set (when this
module detects the BRDY interrupt status in at least
one pipe among the pipes for which software
enables the BRDY interrupt output).
For the conditions for PIPEBRDY status assertion,
refer to (1) BRDY Interrupts under section 17.4.2,
Interrupt Functions.
This module clears this bit to 0 when software writes
0 to all the PIPEBRDY bits corresponding to the
PIPEBRDYE bits to which 1 has been set.
This bit cannot be cleared to 0 even if software writes
0 to this bit.
VBUS Input Status
0: The VBUS pin is low level.
1: The VBUS pin is high level.
Device State
000: Powered state
001: Default state
010: Address state
011: Configured state
1xx: Suspended state
When the host controller function is selected, the
read value is invalid.
