USBX_Init_t Struct Reference

USBXpress

16-bit Vendor ID to be returned to the host's Operating System during USB enumeration.

Set to 0x10C4 to use the default Silicon Laboratories Vendor ID.

16-bit Product ID to be returned to the host's Operating System during USB enumeration.

Set to 0xEA61 to associate with the default VCP driver.

Pointer to a character string.

See AN571 Appendix B for formatting. NULL pointer will be treated as a valid address.

Specifies how much bus current a device requires.

Set to one half the number of milliamperes required. The maximum allowed current is 500 milliamperes, and hence any value above 0xFA will be automatically set to 0xFA. Example: Set to 0x32 to request 100 mA.

Set bit 6 to 1 if the device is self- powered and to 0 if it is bus-powered.

Set bit 5 to 1 if the device supports the remote wakeup feature. Bits 0 through 4 must be 0 and bit 7 must be 1. Example: Set to 0x80 to specify a bus-powered device that does not support remote wakeup.

The device's release number in BCD (binary-coded decimal) format.

In BCD, the upper byte represents the integer, the next four bits are tenths, and the final four bits are hundredths. Example: 2.13 is denoted by 0x0213.

Whether to use the USB FIFO space to store VCP variables or else store them in user XRAM.

The addresses of the variables are the same either way. If the current device does not support the use of the USB FIFO space form variable storage, this option does nothing.
