• ADC clock output control (ADCK_ENB)
ADCK_ENB = 0: Output clock is enabled
ADCK_ENB = 1: Output clock is disabled (HZ)
• ADC clock output inverting control (ADCK_INV)
ADCK_INV = 0: Default ADC_CK and ADC_CKB output
ADCK_INV = 1: Inverted ADC_CK and ADC_CKB output
• ADC clock selection control (ADCK_SEL)
ADCK_SEL = 0: Internal PLL output is used
ADCK_SEL = 1: External clock (ADC_CKEX) is used
• ADC output buffer state control (ADOM)
ADOM<1:0>
