CONFIG_SOC_ATMEL_SAM4S_PLLA_DIVA¶
PLL DIVA
Type: hex
Help¶
This is the divider (DIVA) used by the PLL. The processor clock is (MAINCK * (MULA + 1) / DIVA).
Board config file can override this settings for a particular board.
With default of MULA == 9, and DIVA == 1, PLL is running at 10 times of main clock.
Direct dependencies¶
SOC_SERIES_SAM4S && SOC_FAMILY_SAM
(Includes any dependencies from if’s and menus.)
Defaults¶
- 0x01 if
SOC_SERIES_SAM4S&&SOC_FAMILY_SAM
