(5) CPU_DTLN (CPU_FIFO Receive Data Length Register) Bits (b10~b0)
These bits are valid against the endpoint set to the OUT buffer (EPi_DIR bit = “0”) and indicates the receive
data number (byte count) in the CPU side buffer.
Further, these bits are set to execute countdown when the CPU_FIFO Data Register is read out. This
operation changes according to the RCNT bit of the CPU_FIFO Select Register. For details, refer to “RCNT
bit”.
These bits indicate the valid value when the Creq bit of this register is equal to “0”.
