+# ESP Hardware Abstraction Layer for PCNT Peripherals
+
+> [!NOTE]
+> This component is currently in beta. Its API, behavior, and compatibility may change at any time and without notice; backward compatibility is not guaranteed. Use caution when integrating into production systems.
+
+## Overview
+
+The `esp_hal_pcnt` component provides a **Hardware Abstraction Layer** for PCNT (Pulse Counter) peripherals across ESP-IDF supported targets. This HAL enables efficient counting of external pulses and signals, with support for quadrature encoders, frequency measurement, and position tracking applications.
+
+## Architecture
+
+The PCNT HAL is structured in two main sub-layers:
+
+1. **HAL Layer (Upper)**: Defines the operational steps and data structures required to control PCNT peripherals (e.g., initialization).
+
+2. **Low-Level Layer (Bottom)**: Serves as a translation layer between the HAL and the register files defined in the `soc` component, handling target-specific register configurations.
+
+## Features
+
+### Core Counting Features
+- Bidirectional pulse counting (increment/decrement)
+- Configurable counting range with high/low limits
+- Counter value read operations
+- Counter clear and reset functionality
+- Start/stop control for counting operations
+
+### Channel Configuration
+- Edge action configuration:
+  - Hold: Keep current count value
+  - Increase: Increment count value
+  - Decrease: Decrement count value
+- Level action configuration:
+  - Keep: Maintain current count mode
+  - Inverse: Invert count direction
+  - Hold: Freeze count value
+
+### Event Detection
+- Threshold events
+- High/low limit events
+- Zero-crossing events
+- Watch-point events
+- Step events
+
+### Signal Processing
+- Glitch filtering with configurable filter width
+  
+## Usage
+
+The HAL functions primarily serve ESP-IDF PCNT peripheral drivers such as `esp_driver_pcnt` component.
+
+Advanced developers can use these interfaces directly when implementing custom pulse counting applications, with the understanding that API stability is not guaranteed.
+
+## Dependencies
+
+- `soc`: Provides chip-specific register definitions and peripheral capabilities
+- `hal`: Core hardware abstraction utilities and macros
