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.

A system for collecting servo field data from programmable devices in embedded disk controllers, comprising:
- a servo controller with a read channel interface wherein the read channel interface comprising:
- 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, wherein 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.
A method for collecting servo field data from programmable devices in embedded disk controllers, comprising:
- receiving a servo field detection signal, wherein the servo field detection signal is received by a programmable control logic in a read channel interface in a servo controller and 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 a read channel device;
- receiving control signal for capturing servo field data;
- and
- organizing servo field data.
