Detailed Description

KSZ8851SNL SPI Ethernet Controller driver.

The KSZ8851SNL is a single-chip ethernet controller which supports 10/100 Mbps full and half-duplex communication. It has integrated 12KiB RX FIFO and a 6KiB TX FIFO and it is controlled using SPI. This module contains functions for the necessary SPI commands for reading/writing registers and reading from and writing to the FIFOs.

void KSZ8851SNL_SPI_ReadFifo	(	int	`numBytes,`
		uint8_t *	`data`
	)

Read data from the ethernet controller RX FIFO.

Make sure that the ethernet controller is in DMA mode before calling this function. This is configured by setting bit 3 in the RXQCR register. This bit should also be cleared whenever you want to access the control registers.

When reading data from the controller the first 4 bytes is always dummy data and is skipped by this function.

Parameters

[in]	`numBytes`	Number of bytes to read, 1-12K
[out]	`data`	Buffer where the bytes are inserted.

void KSZ8851SNL_SPI_WriteRegister	(	uint8_t	`reg,`
		uint16_t	`value`
	)

Write ethernet controller register.

Parameters

[in]	`reg`	Register to write
[in]	`value`	The value to be written into the register

void KSZ8851SNL_Transmit	(	uint16_t	`length,`
		const uint8_t *	`buffer`
	)

Transmit a chunk of data to the ethernet controller. The chunk can be either a full ethernet frame or a partial chunk of an ethernet frame.

Note: If the ethernet packet is divided into several packet buffers then this function should be called for each chunk in order.

Parameters

[in]	`length`	the length of the data buffer to be transmitted
[in]	`buffer`	the buffer that contains data to be transmitted

Definition at line 823 of file ksz8851snl.c .

bool KSZ8851SNL_TransmitBegin ( uint16_t length )

Prepares for a transmission of an ethernet frame over the network.

Parameters

[in] length the length of frame to be transmitted

Returns: true if transmission is initialized, false if there is not enough tx memory left on the ethernet controller.

Definition at line 762 of file ksz8851snl.c .

void KSZ8851SNL_TransmitEnd ( uint16_t length )

Ends a transmission of an ethernet frame to the ethernet controller.

This will make sure that data is correctly padded. And will not return until the packet is sent.

Parameters

[in] length the length of the complete frame. This is needed so we can pad the transmission to a 4 byte boundary

static uint32_t MIBCountersRead ( uint16_t offset )

static

helper function for KSZ8851SNL_UpdateMIBCounters

Parameters

[in] offset The offset specifies which MIB counter you want to read

Returns: The value of the MIB Counter

Definition at line 389 of file ksz8851snl.c .

static void ReleaseIncosistentFrame ( void )

static

Release the current frame if it is inconsistent.

Note: Support method used for minimizing the code size.

Variable Documentation

KSZ8851SLN_mib_t mibCounters

static

Copy of the current MIB counters values from the ksz8851snl. This is updated by calling KSZ8851SNL_MIBCountersUpdate .

The datasheet recommends that the MIB counter values are read at least every 30 seconds because of counter overflow possibility.
