19.6.2 OTG Dual Role “A” Device Operation
DS0200-003
A_WAIT_VRISE
A_WAIT_VFALL
A_WAIT_BCON
A_PERIPHERAL
A_SUSPEND
A dual role “A” device will operate as the following flow diagram and state description table illustrates.
A_HOST
A_IDLE
State
Action
If ID Interrupt, cable was unplugged or type B cable attached. Goto B_IDLE
If the “A” application wants to use the bus or if the “B” device is doing an SRP as indicated by
either an A_SESSV Interrupt or Attach or Port Status Change Interrupt check data line for 5 –10
ms pulsing, Go to A_WAIT_VRISE, turn on DRV_VBUS
If ID Interrupt or if AVBUSV is false after 100 ms, cable has been changed or the “A” device
cannot support the current required from the “B” device, Go to A_WAIT_VFALL, turn off
DRV_VBUS
If AVBUSV, interrupt, Go to A_WAIT_FALL, turn off DRV_VBUS
200 ms without Attach or ID Interrupt, Go to A_WAIT_FALL, turn off DRV_VBUS
AVBUSV Interrupt and “B” device attaches, Go to A_HOST, turn on Host Mode
Enumerate Device determine OTG Support
If AVBUSV/ Interrupt or “A” device is done and doesn’t think he wants to do something soon or
the “B” device disconnects, Go to A_WAIT_VFALL. Turn off Host Mode and DRV_BUS
If the “A” device is finished with session or it wants to allow “B” device to take bus, Goto
A_SUSPEND
ID Interrupt or the “B” device disconnects, Goto A_WAIT_BCON
If ID Interrupt, or if 150 ms “B” disconnect timeout (This timeout value could be longer.) or if
AVBUSV\ Interrupt, Goto A_WAIT_VFALL, urn off DRV_VBUS
If HNP enabled, and “B” disconnects in 150 ms then “B” device is becoming the host, Goto
A_PERIPHERAL, urn off Host Mode
If “A” wants to start another session, goto A_HOST
If ID Interrupt or if AVBUSV interrupt, Goto A_WAIT_VFALL, turn off DRV_VBUS.
If 3 –200 ms of Bus Idle, Go to A_WAIT_BCON, Turn on Host Mode
If ID Interrupt or (A_SESSV/ & b_conn/), Go to A_IDLE
