37 I/O 1.8 V. When VREN is high, 1.8 V must be applied externally to provide current for the core during
suspend.

(1) During normal operation, the internal 3.3- to 1.8-V voltage regulator of the TUSB3210 is enabled and provides power to the core. To
save power during the suspend mode, the internal regulator is disabled. In this case, the pin becomes an input, and a simple external
power source is required to provide power to the core. This source needs to supply a limited amount of power (10 μ A maximum) within
the voltage range of 1 to 1.95 V.
(2) All open-drain output pins can sink up to 8 mA.
