Detailed Description

Board-specific pinctrl description consumed by platform setup code.

Implement this once per BSP and return stable references to immutable signal groups. Grouping by peripheral gives bus/HAL initialization a typed contract; describing pull, direction, and active level here keeps electrical facts out of application logic and prevents a platform driver from guessing board pins.

Constructor & Destructor Documentation

~Pins()

virtual ersa::board::Pins::~Pins ( )

virtualdefault

Permit destruction through the common pin-map contract.
