CONFIG_SOC_ATMEL_SAM3X_PLLA_MULA

(No prompt – not directly user assignable.)

Type: hex

Help

This is the multiplier (MULA) 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 == 6, and DIVA == 1, PLL is running at 7 times of main clock.
