2.1.23.1 Initialization Clock (SLOWCLK)

The initialization clock (SLOWCLK) defines the system frequency used during initialization. All save operations are performed at this frequency.

The INIT intellectual property (IP) block is designed to operate only at low frequencies during initialization and save operations. This limitation exists because the design contains a large 64‑to‑1 data multiplexer; as the number of connected clients increases, the maximum achievable operating frequency decreases.

The initialization frequency should be kept below 10 MHz. This requirement is application‑dependent unless the Analog Configuration multiplexer (ACM) port interface is accessed.

When the Flash Memory Block is used to initialize the Analog System Builder, the initialization frequency must be less than 10 MHz, because initialization accesses the ACM port interface.
