Description
Indicates control register 0.
Reserved, always write 0.
Sampling rate, CKS = ICLK0 ÷ (CDIV3 x 125).
Sampling rate, CKS = ICLK0 ÷ 256. (Note: CDIV3 must be set to 2.)
Sampling rate, CKS = ICLK0 ÷ 1458. (Note: CDIV3 must be set to 12.)
Sampling rate, CKS = ICLK0 ÷ (125 x M + S x N). See Section 4.5 on page 16.
