General purpose I/O pin status –
If GPIOXOE = 1 (X: 0 ~ 6), 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 6 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 GL652USB can be exposed without permanently
damaging it. The GL652USB contains circuitry to protect the inputs against damage from high static
voltages; however, do not apply voltages higher than those shown in the table. Keep V_IN and V_OUT within
the range GND ≤ (V_IN or V_OUT) ≤ V_CC. Connect unused inputs to the appropriate voltage level, either GND
or V_DD.
