Other Parts Discussed in Thread: TUSB1064,
Hello there,
I intend to use a TPS65987D to control a TUSB1064 Mux. The TUSB1064 output signals are used in a HUB circuit (TUSB8044) and in a TUSB1046. I need to make sure that the TUSB1064 never enters the configuration in which the RX/TX inputs are "directed" only to the TUSB1046, as follows:
As it can be seen in the TUSB1064 datasheet, when operating in the GPIO Configuration Mode, the selection signal CTL0 been pulled High would mean that it would never enter this state. Can I simply pull the CTL0 pin to High, to make sure it never "bypasses" the HUB? If not, then how could I make sure it never enters this configuration? Also, is there a similar solution to this problem if I decide to use the TUSB1064 in the I²C configuration Mode?
Thanks,
Eduardo Alves
