Detailed Description

Macros for pin control configuration of Renesas RA SoCs.

Each pin configuration is built with the RA_PSEL() macro, which combines a peripheral-function selector, the port number, and the pin number within that port.

The selector follows the naming convention RA_PSEL_<FUNCTION>, where <FUNCTION> is one of:

• Analog: ADC, DAC, ACMPHS, ACMPHS_VCOUT, CAC_ADC, CAC_DAC, CTSU
• Timers: AGT, GPT0, GPT1
• Serial: SCI_0 ... SCI_9, SPI, I2C, I3C
• Connectivity: CANFD, QSPI, OSPI, SSIE, USBFS, USBHS, SDHI, ETH_MII, ETH_RMII, ETH_RGMII
• Graphics / capture: GLCDC, CEU
• System: HIZ_JTAG_SWD, CLKOUT_RTC, ETHPHYCLK, BUS

#include <zephyr/dt-bindings/pinctrl/renesas/pinctrl-ra.h>

                group1 {
                        psels = <RA_PSEL(RA_PSEL_SCI_0, 4, 11)>,
                                <RA_PSEL(RA_PSEL_SCI_0, 4, 10)>;
                };
        };
};

Macro Definition Documentation

RA_PSEL

#define RA_PSEL	(		psel,
			port_num,
			pin_num )

#include <zephyr/dt-bindings/pinctrl/renesas/pinctrl-ra.h>

Value:

(1 << RA_MODE_POS | psel << RA_PSEL_POS | port_num << RA_PORT_NUM_POS |                    \
 pin_num << RA_PIN_NUM_POS)

Macro to encode a pin configuration for Renesas RA SoCs.

This macro encodes the mode, peripheral selection (PSEL), port number, and pin number into a single 32-bit value suitable for use in DeviceTree pinctrl configurations.

Parameters

psel	Peripheral selection value (use RA_PSEL_* macros).
port_num	Port number.
pin_num	Pin number within the port.

Returns

Encoded pin configuration value.
