RDC_SEMA42_Init()

void RDC_SEMA42_Init

(

RDC_SEMAPHORE_Type *

base

)

Initializes the RDC_SEMA42 module.

This function initializes the RDC_SEMA42 module. It only enables the clock but does not reset the gates because the module might be used by other processors at the same time. To reset the gates, call either RDC_SEMA42_ResetGate or RDC_SEMA42_ResetAllGates function.

Parameters

base	RDC_SEMA42 peripheral base address.

RDC_SEMA42_Lock()

void RDC_SEMA42_Lock	(	RDC_SEMAPHORE_Type *	base,
		uint8_t	gateNum,
		uint8_t	masterIndex,
		uint8_t	domainId
	)

Locks the RDC_SEMA42 gate.

This function locks the specific RDC_SEMA42 gate. If the gate has been locked by other processors, this function waits until it is unlocked and then lock it.

Parameters

base	RDC_SEMA42 peripheral base address.
gateNum	Gate number to lock.
masterIndex	Current processor master index.
domainId	Current processor domain ID.
