UART Registers
19.5.1.42 Transmit Frame Length Low Register (TXFLL)
The transmit frame length low register (TXFLL) and the TXFLH register hold the 13-bit transmit frame
length (expressed in bytes). TXFLL holds the LSBs and TXFLH holds the MSBs. The frame length value is
used if the frame length method of frame closing is used. The transmit frame length low register (TXFLL)
is shown in
and described in
