Abstract:
A controller coupled to a redundant array of inexpensive disks (RAID) includes a processor and a non-volatile memory element. The processor has an input/output port that is configurable in one of an open-drain driver configuration, a high-impedance driver configuration and a totem-pole driver configuration. The totem-pole driver configuration is capable of supplying sufficient current to operate a slave device coupled to the input/output port. Firmware stored in the non-volatile memory device dynamically adjusts the driver configuration to prevent negative voltage swings in a signal communicated via the input/output port.
