Write Protection
______________________________________
1
Writing into memory locations beyond address offset 0x96 must be avoided
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. 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.
