CK_DIV

Internal Multiple-Frequency Clock Divider

CK_DIV divides a user-provided external clock signal with different divide factors on either or both of the outputs. Only one CK_DIV may be used per design. The CK_DIV is not available if the OSC5 element is used.

The clock frequencies of the OSC1 and OSC2 outputs are determined by specifying the DIVIDE1_BY=n₁ attribute for the OSC1 output and the DIVIDE2_BY=n₂ attribute for the OSC2 output. n₁ and n₂ are integer numbers by which the clock input (C) is divided to produce the desired output clock frequency. The available values of n₁ and n₂ are shown in the following table.
