Abstract
A system for collecting servo field data from programmable devices in embedded disk controllers. The system includes a servo controller with a read channel interface. The read channel interface includes a programmable control logic that receives a servo field detected signal from a module that detects a servo field start bit; and a register in the read channel interface that is enabled by the programmable control logic for receiving servo field data from a read channel device. The programmable control logic is configured to operate both in a two wire mode and in a three wire mode allowing the servo controller to process servo data from the read channel device.
