Module lpc845_pac::adc0::ctrl [−][src]
Expand description
ADC Control register. Contains the clock divide value, resolution selection, sampling time selection, and mode controls.
Structs
Field ASYNMODE
reader - Select clock mode.
Field ASYNMODE
writer - Select clock mode.
Field CALMODE
reader - Writing a ‘1’ to this bit will initiate a sef-calibration cycle. This bit will be automatically cleared by hardware after the calibration cycle is complete. Note: Other bits of this register may be written to concurrently with setting this bit, however once this bit has been set no further writes to this register are permitted unitl the full calibration cycle has ended.

Field CLKDIV
reader - In synchronous mode only, the system clock is divided by this value plus one to produce the clock for the ADC converter, which should be less than or equal to 72 MHz. Typically, software should program the smallest value in this field that yields this maximum clock rate or slightly less, but in certain cases (such as a high-impedance analog source) a slower clock may be desirable. This field is ignored in the asynchronous operating mode.
