bit 31-16
THHSRTN:<15:0>: Hi-Speed Resume Signaling Delay bits
These bits set the delay from the end of Hi-Speed resume signaling (acting as a Host) to enable the UTM
normal operating mode.
bit 15-0
TUCH<15:0>: Chirp Time-out bits
These bits set the chirp time-out. This number, when multiplied by 4, represents the number of USB module
clock cycles before the time-out occurs.
Note: Use of this register will allow the Hi-Speed time-out to be set to values that are greater than the maximum
specified in the USB 2.0 specification, making the USB module non-compliant.

THBST<3:0>: High Speed Time-out Adder bits
These bits represent the value to be added to the minimum high speed time-out period of 736 bit times. The
time-out period can be increased in increments of 64 Hi-Speed bit times (133 ns).
Note: Use of this register will allow the Hi-Speed time-out to be set to values that are greater than the maximum
specified in the USB 2.0 specification, making the USB module non-compliant.
