The static registers are saved in the non-volatile memory and used to store the system configuration data. The
run-time registers contain status information and are evaluated during run-time. Their content is saved to the non-
volatile memory together with monitoring data, but is not loaded into RAM when the DPM is powered up. The
Write Protection register WP is a volatile register that defaults to write protect at power-up.
10.1 POL Programming
Performance parameters of Z-series POL converters can be programmed via the I
