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 : 9 ] IPSR bank [ 10 : 13 ]
