You are an expert Verilog hardware designer working on a complete FPGA or ASIC project. You are given the full source code of a Verilog project. One of the modules in the project is incomplete — its implementation is missing and marked with:

// >>> Module Implementation Begin

// <<< Module Implementation End

Your task is to complete the missing implementation so that the entire project functions correctly. You must infer what the missing module or logic is supposed to do by analyzing the rest of the codebase: module names, signal connections, instantiations, comments, and usage patterns.

Follow these rules:

1. Only generate Verilog code to go between the `// >>> Module Implementation Begin` and `// <<< Module Implementation End` comments.
2. Use Verilog-2001 syntax. Ensure the code is synthesizable.
3. Assume the goal is a working, integrated hardware design — your code must make the whole system function as intended.
4. Analyze the naming, I/O ports, and how the module is instantiated or used in other parts of the project.
5. Implement correct behavior based on design context. Do not guess randomly — reason it out.
6. Avoid vendor-specific features unless explicitly required.
7. Do not output comments, explanation, or anything outside the required code region unless explicitly asked.

Your output should contain **only the Verilog code** that fits inside the marked region.

/**
 * gamepad_pmod_driver -- Serial interface for the Gamepad Pmod.
 *
 * This module reads raw data from the Gamepad Pmod *serially*
 * and stores it in a shift register. When the latch signal is received, 
 * the data is transferred into `data_reg` for further processing.
 *
 * Functionality:
 *   - Synchronizes the `pmod_data`, `pmod_clk`, and `pmod_latch` signals 
 *     to the system clock domain.
 *   - Captures serial data on each falling edge of `pmod_clk`.
 *   - Transfers the shifted data into `data_reg` when `pmod_latch` goes low.
 *
 * Parameters:
 *   - `BIT_WIDTH`: Defines the width of `data_reg` (default: 24 bits).
 *
 * Inputs:
 *   - `rst_n`: Active-low reset.
 *   - `clk`: System clock.
 *   - `pmod_data`: Serial data input from the Pmod.
 *   - `pmod_clk`: Serial clock from the Pmod.
 *   - `pmod_latch`: Latch signal indicating the end of data transmission.
 *
 * Outputs:
 *   - `data_reg`: Captured parallel data after shifting is complete.
