CONFIG_UART_NS16550_DLF¶
Enable Divisor Latch Fraction (DLF) support
Type: bool
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¶
(SERIAL && SOC_ARC_IOT) || (UART_NS16550 && SERIAL)
(Includes any dependencies from if’s and menus.)
Defaults¶
- “y” if
