Help¶

This enables support for divisor latch fraction (DLF). It is used to limit frequency error.

Says n if you are not sure if hardware supports this.

Direct dependencies¶

UART_NS16550 && SERIAL

(Includes any dependencies from if’s and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
