The TUSB3410 device can be brought out of the suspended state, or woken up, by a command from the host. The TUSB3410 device also supports remote wakeup and can be awakened by either of two input signals. A low pulse on the WAKEUP terminal or a low-to-high transition on the RI/CP terminal wakes up the device.
NOTE
For reliable operation, either condition must persist for approximately 3-ms minimum, which allows time for the crystal to power up because in the suspend mode, the crystal interface is powered down. The state of the WAKEUP or RI/CP terminal is then sampled by the clock to verify there was a valid wake-up event.
There are three requirements for the reset signal timing. First, the minimum reset pulse duration is 100 μs. At power up, this time is measured from the time the power ramps up to 90% of the nominal VCC until the reset signal exceeds 1.2 V. The second requirement is that the clock must be valid during the last 60 µs of the reset window. The third requirement is that, according to the USB specification, the device must be ready to respond to the host within 100 ms. This means that within the 100-ms window, the device must come out of reset, load any pertinent data from the I2C EEPROM device, and transfer execution to the application firmware if any is present. Because the latter two events can require significant time, the amount of which can change from system to system, TI recommends having the device come out of reset within 30 ms, leaving 70 ms for the other events to complete. This means the reset signal must rise to
1.8 V within 30 ms.
These requirements are depicted in Figure 4-1. When using a 12-MHz crystal, the clock signal may take several milliseconds to ramp up and become valid after power up. Therefore, the reset window may need to be elongated up to 10 ms or more to ensure that there is a 60-µs overlap with a valid clock.
