摘要
A control unit for power supply circuits of points of load (POL) of an electronic system includes a means for autonomous customization by the customer-user of the original control program residing in the ROM of the device, as well as configuration of control parameters of the POL. Microprocessor architecture of the device includes a dedicated logic block and a rewritable non-volatile memory coupled to the data bus of the device or to an auxiliary bus thereof, thus providing a means for software extension of the power supply circuits. RAM is loaded at start-up with data of modified or added routines for implementing new commands and values of configuration and control data of the POL. The RAM may optionally be subjected to encryption/decryption for protection. During operation, program execution jumps from ROM address space to RAM address space and vice versa when certain values of a program counter are reached.
