TX2 / TX2UL as USB Host controller
Can we use the TX2 /TX2UL as USB Host controller?
No. The TX2 / TX2UL device (CY7C68000 / CY7C68003) cannot be used as USB Host controller since it does not have two important features which are required so that it can be used as a Host Controller.
The important features are:
1) Ability to determine the speed of the device connected. If a high speed device is connected, the host must be able to detect chirp sequence from the host end.
2) The host must have a circuitry to detect connect and disconnect event.
