NO.
Clock and Reset Signals
GRSTz
50
I, PU
Global power reset. This reset brings all of the TUSB8042A internal registers to the default
states. When GRSTz is asserted, the device is completely nonfunctional.
XI
62
I
Crystal input. This pin is the crystal input for the internal oscillator. The input can alternately be
driven by the output of an external oscillator. When using a crystal, a 1MΩ feedback resistor is
required between XI and XO.
XO
61
O
Crystal output. This pin is the crystal output for the internal oscillator. If XI is driven by an
external oscillator, this pin can be left unconnected. When using a crystal, a 1MΩ feedback
resistor is required between XI and XO.
