25.5 CLB Clock Selection

The CLB module clock source can be selected using the CLB Clock Selection (CLKSEL) bits. Available clock sources include internal signals from select oscillator or timer resources, and external sources such as crystal oscillators. Additionally, the CLBCLKPPS input that can be used as an external clock source to the module.

The CLB Clock Prescaler Selection (CLKPRE) bits provide clock divider selections. The output of the clock divider circuit (BLE_clk) is connected to all 128 BLE output flops and as a clock source to the CLBSWIN registers.
