This field indicates the state of the USBB.
Finite State Machine Status Register
Description
a_idle state: this is the start state for A-devices (when the ID pin is 0)
a_wait_vrise: In this state, the A-device waits for the voltage on VBus to rise above the A-
device VBus Valid threshold (4.4 V).
a_wait_bcon: In this state, the A-device waits for the B-device to signal a connection.
a_host: In this state, the A-device that operates in Host mode is operational.
a_suspend: The A-device operating as a host is in the suspend mode.
a_peripheral: The A-device operates as a peripheral.
a_wait_vfall: In this state, the A-device waits for the voltage on VBus to drop below the A-
device Session Valid threshold (1.4 V).
a_vbus_err: In this state, the A-device waits for recovery of the over-current condition that
caused it to enter this state.
a_wait_discharge: In this state, the A-device waits for the data usb line to discharge (100 us).
b_idle: this is the start state for B-device (when the ID pin is 1).
b_peripheral: In this state, the B-device acts as the peripheral.
b_wait_begin_hnp: In this state, the B-device is in suspend mode and waits until 3 ms before
initiating the HNP protocol if requested.
b_wait_discharge: In this state, the B-device waits for the data usb line to discharge (100 us)
before becoming Host.
