UART FIFO DMA Mode

In the specification, the possible values for the DMA Mode are not listed, as for example for FIFO enable 0/1. Is this an error in the specification, or it is a way to say something not written ? How do you interpret the missing values? and the DMA Mode description?

"UARTn FIFO Control Register

Bit Symbol

0       FIFO Enable           0/1 Active high enable for both UARTn Rx and TX FIFOs and UnFCR[7:1] access.
                                               This bit must be set for proper UART operation. Any transition on this bit will
                                               automatically clear the related UART FIFOs.

3 DMA Mode When the FIFO enable bit (bit 0 of this register) is set, this bit selects the DMA

Hi,Hai Maio,

I am sorry for the delay.

Can you tell me the reference Manual name for the question or the part number you are using?
