General purpose I/O pin status –

If GPIOXOE = 1 (X: 0 ~ 3), GPIOX is driven with the level of internal GPIOXD latch, which

is the same as corresponding GPIOXD bit. If GPIOXOE = 0, GPIOXD reflects the level of

GPIOX pin, which may be different from internal GPIOXD latch. The value written to GPIOD

will be stored in an internal latch, no matter what direction the GPIOX pins are in. Bits 3 to 0

have been pre-assigned specific functions for LED indicators. (active low).

USB device status registers. Procedure to set the device address:

1. After USB reset, the device responds to default address 0, and hub configuration = 0.

2. USB host controller issues SET_ADDRESS request to the device. (INTRB asserted)

3. Micro-controller recognizes the request, then set DEVADR register with appropriate value.

4. Micro-controller prepares the status stage of SET_ADDRESS request by programming

TXCTL0 register.

5. When the hub configuration value is not equal zero, HCONFIG is set to one.

USB reset will clear this register.

6 MAXIMUM RATINGS

Maximum ratings are the extreme limits to which the GL650USB/GL650USB-A can be exposed without

permanently damaging it. The GL650USB/GL650USB-A contain circuitry to protect the inputs against

damage from high static voltages; however, do not apply voltages higher than those shown in the table.

Keep VIN and VOUT within the range GND ≤ (VIN or VOUT) ≤ VCC. Connect unused inputs to the appropriate

voltage level, either GND or VDD.
