USB Finite State Machine Status Register (USBFSM)
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 overcurrent 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.
