XR21V1410
1-CH FULL-SPEED USB UART
The I
the V1410 for configuration.
The SDA and SCL are used to specify whether Remote Wakeup and/or Bus Powered configurations are to be
supported. These pins are sampled at power-up. The following table describes how Remote Wakeup and Bus
Powered support.
The I
well as other attributes and maximum power consumption. The EEPROM must contain 8 bytes of data as
specified in
These values are uploaded from the EEPROM to the corresponding USB Standard Device Descriptor or
Standard Configuration Descriptor. For details of the USB Descriptors, refer to the USB 2.0 specifications.
The Vendor ID value replaces the idVendor field in the USB Standard Device Descriptor.
The Product ID value replaces the idProduct field in the USB Standard Device Descriptor.
The Device Attributes value replaces the bmAttributes field in the USB Standard Configuration Descriptor. The
default setting in the V1410 device is 0xA0. The bit field definitions are:
