Crystal Oscillator Control

Structs

• CTRL_SPEC
  Crystal Oscillator Control

Enums

• ENABLE_A
  On power-up this field is initialised to DISABLE and the chip runs from the ROSC.
  If the chip has subsequently been programmed to run from the XOSC then setting this field to DISABLE may lock-up the chip. If this is a concern then run the clk_ref from the ROSC and enable the clk_sys RESUS feature.
  The 12-bit code is intended to give some protection against accidental writes. An invalid setting will enable the oscillator.
• FREQ_RANGE_A
  Frequency range. This resets to 0xAA0 and cannot be changed.

Type Aliases

• ENABLE_R
  Field ENABLE reader - On power-up this field is initialised to DISABLE and the chip runs from the ROSC.
  If the chip has subsequently been programmed to run from the XOSC then setting this field to DISABLE may lock-up the chip. If this is a concern then run the clk_ref from the ROSC and enable the clk_sys RESUS feature.

• ENABLE_W
  Field ENABLE writer - On power-up this field is initialised to DISABLE and the chip runs from the ROSC.
  If the chip has subsequently been programmed to run from the XOSC then setting this field to DISABLE may lock-up the chip. If this is a concern then run the clk_ref from the ROSC and enable the clk_sys RESUS feature.
