  *  @defgroup FPGA FPGA
  *  @brief FPGA service module.
- *  Maintains latest sensor readings at priority task interval.  Updates actuator
- *  states at priority task interval.
+ *  The FPGA module manages communication between the HD and the FPGA via UART.
+ *  This module is driven by the Priority Task via calls to two FPGA executive functions:
+ *     1) an incoming executive manages the states of the state machine that deal with responses and data received from the FPGA
+ *     2) an outgoing executive manages transmission of write and read commands to the FPGA.
+ *  This module first reads the header record that includes the FPGA ID and revision and
+ *  verifies the FPGA ID to check FPGA communication.  It then initializes and configures the ADCs and
+ *  various other sensors that are interfaced via the FPGA. Then, it essentially enters an infinite loop
+ *  where a bulk write command updates actuator set points and a bulk read command retrieves the latest sensor readings.
