EM32F967_GPIO

#define EM32F967_GPIO   0 /* 000: GPIO function */

EM32F967 Pin Control Definitions (STM32-style).

This header defines the pin control macros for the EM32F967 microcontroller following the STM32 pinctrl design pattern. Based on EM32F967_Complete_Specification_v1.0.md

EM32F967_MUX_MASK

#define EM32F967_MUX_MASK   0x7U

EM32F967_MUX_SHIFT

#define EM32F967_MUX_SHIFT   0U

Pin configuration bit field encoding (STM32-style).

Fields:

• mux [ 0 : 2 ] - Multiplexing function (3 bits)
• pin [ 3 : 6 ] - Pin number (4 bits, 0-15)
• port [ 7 : 7 ] - Port identifier (1 bit, 0=PA, 1=PB)

This encoding allows up to 2 ports, 16 pins per port, and 8 mux functions
