Abstract
A data storage drive has two controllers with respective digital control outputs and serial channels. The drive has a serial test channel operable to communicate with a testing system. A switching circuit is coupled to the digital control outputs, the serial channels, and the serial test channel. The switching circuit is configured to, in response to respective combinations of binary values set via the digital control outputs, switch lines of the serial test channel between the respective serial channels of the controllers. The controllers are configured to set the combinations of binary values in response to one or more command received via a receive line of the serial test channel.
