DATASHEET
USB2513/13i and USB2514/14i Only: The LED_A[x:1]_N pins are sampled after RESET_N negation,
and the logic values are used to configure the hub if the internal default configuration mode is selected.
The implementation shown in Figure 8.5 shows a recommended passive scheme. When a pin is
configured with a "Strap High" configuration, the LED functions with active low signaling, and the PAD
will "sink" the current from the external supply. When a pin is configured with a "Strap Low"
configuration, the LED functions with active high signaling, and the PAD will source the current to the
external LED.
8.7
Reset
There are two different resets that the hub experiences. One is a hardware reset via the RESET_N
pin and the second is a USB Bus Reset.
8.7.1
External Hardware RESET_N
A valid hardware reset is defined as assertion of RESET_N for a minimum of 1
μs after all power
supplies are within operating range. While reset is asserted, the hub (and its associated external
circuitry) consumes less than 500
μA of current from the upstream USB power source.
Assertion of RESET_N (external pin) causes the following:
1. All downstream ports are disabled, and PRTPWR power to downstream devices is removed (unless
BC_EN is enabled).
2. The PHYs are disabled, and the differential pairs will be in a high-impedance state.
3. All transactions immediately terminate; no states are saved.
4. All internal registers return to the default state (in most cases, 00(h)).
5. The external crystal oscillator is halted.
6. The PLL is halted.
The hub is “operational” 500
μs after RESET_N is negated. Once operational, the hub immediately
reads OEM-specific data from the external EEPROM (if the SMBus option is not disabled).
