(9) UF0 configuration register (UF0CNF)
This register stores the value that is to be returned in response to the GET_CONFIGURATION request.
This register is read-only, in 8-bit units.
When the SET_CONFIGURATION request is received, its wValue is automatically written to this register.
When a change of the value of this register from 00H to other than 00H is detected, the CONF bit of the UF0MODS
register is set to 1. If the SET_CONFIGURATION request is processed by FW, the status of this register is
immediately reflected on the UF0MODS register as soon as data has been written to this register (CONF bit = 1
before completion of the status stage).
Caution Do not execute a write access to this register. If written, the operation is not guaranteed.
