| config SOC_ATMEL_SAME70_EXT_SLCK |
| bool "Use external crystal oscillator for slow clock" |
| help |
| Say y if you want to use external 32 kHz crystal |
| oscillator to drive the slow clock. Note that this |
| adds a few seconds to boot time, as the crystal |
| needs to stabilize after power-up. |
| |
| Says n if you do not need accurate and precise timers. |
| The slow clock will be driven by the internal fast |
| RC oscillator running at 32 kHz. |

| config SOC_ATMEL_SAME70_EXT_MAINCK |
| bool "Use external crystal oscillator for main clock" |
| help |
| The main clock is being used to drive the PLL, and |
| thus driving the processor clock. |
| |
| Say y if you want to use external crystal oscillator |
| to drive the main clock. Note that this adds about |
| a second to boot time, as the crystal needs to |
| stabilize after power-up. |
| |
| The crystal used here can be from 3 to 20 MHz. |
| |
| Says n here will use the internal fast RC oscillator |
| running at 12 MHz. |

| range 1 62 |
| 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. |
| |
| Setting MULA=0 would disable PLL at boot, this is currently |
| not supported. |
| |
| With default of MULA == 24, and DIVA == 1, |
| PLL is running at 25 times the main clock frequency. |

| For JTAG debugging CPU clock (HCLK) should not stop. In order |
| to achieve this, make CPU go to Wait mode instead of Sleep |
| mode while using external crystal oscillator for main clock. |

| config SOC_ATMEL_SAME70_DISABLE_ERASE_PIN |
| bool "Disable ERASE pin" |
| help |
| At reset ERASE pin is configured in System IO mode. Asserting the ERASE |
| pin at '1' will completely erase Flash memory. Setting this option will |
| switch the pin to general IO mode giving control of the pin to the GPIO |
| module. |
