Detailed Description

Macro definitions for port operations.

This header file contains essential macros for handling port and pin names.

Note

These macros serve to improve code clarity and maintain protocol compliance by providing meaningful names for standard port operation indicators.

Macro Definition Documentation

SET_PIN

#define SET_PIN	(		NUMBER,
			ARGUMENT )

Value:

PIN ## NUMBER ## ARGUMENT

Concatenates pin identifier components into a full pin name.

This macro concatenates the token PIN, the given pin NUMBER, and the specified ARGUMENT to form a complete pin identifier.

For example, SET_PIN(3, _CTRL) expands to PIN3_CTRL.

This is useful for handling pin-related registers or bitfields in a flexible and generic way within embedded code.

Note

The macro uses the token-pasting operator (##), so arguments must be valid tokens suitable for concatenation.

SET_PORT

#define SET_PORT	(		NAME,
			ARGUMENT )

Value:

PORT ## NAME ## ARGUMENT

Concatenates port identifier components into a full port name.

This macro concatenates the token PORT, the given port NAME, and the specified ARGUMENT to form a complete port identifier.

For example, SET_PORT(A, .DIR) expands to PORTA.DIR.

This is useful for handling port-related registers or bitfields in a flexible and generic way within embedded code.

Note

The macro uses the token-pasting operator (##), so arguments must be valid tokens suitable for concatenation.
