The run-time registers contain status information and are evaluated during run-time. The Write Protection register WP is a volatile register that defaults to write protect at power-up. 10.1.3 POL Setup Registers Since the POL converters contain only RAM, the data defining performance parameters for each POL and Auxiliary Device, such as the output voltage, protection thresholds, feedback loop compensation, turn-on and turn- off delays, fault management settings, etc., is stored in the POL setup registers in the DPM. The POL setup registers consist of 23 data bytes and 2 CRC bytes. The Auxiliary Device setup registers occupy the same amount of bytes as a POL converter, but only 3 registers have meaningful data. The other registers should be filled with 0x00. The POL setup registers are listed in Table 2. |
