(12) UF0 descriptor length register (UF0DSCL)
UF0DSCL
Bit position
Caution To rewrite this register, set the EP0NKA bit to 1 before reading the register contents, and
7 to 0
This register stores the length of the value that is to be returned in response to the GET_DESCRIPTOR
Configuration request. The value of this register is the number of bytes of all the descriptors set by the
UF0CIEn register minus 1 (n = 0 to 255). The total descriptor length that is to be returned in response to the
GET_DESCRIPTOR Configuration request is determined according to the value of this register.
This register can be read or written in 8-bit units. However, data can be written to this register only when the
EP0NKA bit is set to 1.
Processing of wLength is automatically controlled. If this register is set to 00H, it means that the descriptor to
be returned is 1 byte long. If the register is set to FFH, a descriptor length of 256 bytes is returned. When a
descriptor exceeding 256 bytes in length is used, set the CDCGDST bit of the UF0MODC register to 1 and
process the GET_DESCRIPTOR request by FW (at this time, the CDCGD bit of the UF0MODS register is also
set to 1).

rewrite the register contents after confirming that the bit has been set, in order to prevent
conflict between a read access and a write access.
