Function Documentation

PN_portFwdCtrl()

int32_t PN_portFwdCtrl	(	PN_Handle	pnHandle,
		uint8_t	portNo,
		uint8_t	portFwdState
	)

API to configure port forwarding state.

The Port Forward configuration provides an option to enable or disable frame forwarding between ethernet ports.

Parameters

pnHandle	[in] PN handle
portNo	[in] Port number (ICSS_EMAC_PORT_1 or ICSS_EMAC_PORT_2)
portFwdState	[in] Port forwarding state. Enable Forwarding: ICSS_EMAC_IOCTL_PORT_FWD_CTRL_ENABLE_CMD (0x00) Disable Forwarding: ICSS_EMAC_IOCTL_PORT_FWD_CTRL_DISABLE_CMD (0x01)

Return values

0	- On success <0 - On failure

PN_clearPruIRQ()

void PN_clearPruIRQ	(	PRUICSS_HwAttrs const *	pruicssHwAttrs,
		uint8_t	irq_num
	)

PN_setBaseClock()

int32_t PN_setBaseClock	(	PN_Handle	pnHandle,
		uint16_t	factor
	)

Sets Profinet base clock in multiples of 31.25us.

Parameters

[in]	pnHandle	Profinet Handle
	factor	Clock send factor: min value 8, max value 128

Return values

Slot	number (>=0)
<0	if failure
