IPSR

#define IPSR	(		bank,
			shift,
			func
	)		(((bank) << 10U) | ((shift) << 4U) | (func))

Utility macro to build IPSR property entry.

IPSR: Peripheral Function Select Register Each IPSR bank can hold 8 cellules of 4 bits coded function.

Parameters

bank	the IPSR register bank.
shift	the bit shift for this alternate function.
func	the 4 bits encoded alternate function.

Function code [ 0 : 3 ] Function shift [ 4 : 8 ] Empty [ 9 ] IPSR bank [ 10 : 14 ] Register index [ 15 : 17 ] (S4 only)

IPSR_DUMMY

#define IPSR_DUMMY   IPnSR(0x1f, 7, 0x1f, 0xf)

Macro to define a dummy IPSR flag for a pin.

This macro is used to define a dummy IPSR flag for a pin in the R-Car PFC driver. It is intended for pins that do not have a specific function defined in IPSR but always act as a peripheral. The dummy IPSR flag ensures that the driver sets the 'peripheral' bit for such pins.

	)		(((bank) * 32U) + (pin))

Utility macro to encode a GPIO capable pin.

Parameters

bank	the GPIO bank
pin	the pin within the GPIO bank (0..31)

(

pin

)

(PIN_NOGPSR_START + pin)

Utility macro to encode a non capable GPIO pin.
