Fnet_cpu

IRQ status descriptor returned by the fnet_cpu_irq_disable() function. Actually it corresponds to the interrupt level mask value.

Invalidates CPU-cache memory.

If the CPU has cache memory, this function invalidates it.
This function is called only if FNET_CFG_CPU_CACHE is 1.

Erases the specified range of the Flash memory.

Parameters:

flash_addr	Address in the Flash to erase from.
bytes	Number of bytes to erase in the Flash memory.

Returns:

This function returns:

• FNET_OK if successful.
• FNET_ERR if failed.

See also:

fnet_cpu_flash_write()

This function attempt to erase the number of bytes bytes beginning at flash_addr.
It should be noted that the Flash is block oriented when erasing. It is not possible to erase a few bytes within a page, the whole page will be erased. The flash_addr parameter may be anywhere within the first page to be erased and flash_addr+ bytes may be anywhere in the last block to be erased.

Writes the specified data to the Flash memory.

Parameters:

dest	Destination address in the Flash to write to.
data	Pointer to the block of data to write to the Flash memory Size of the data block must be equal to FNET_CFG_CPU_FLASH_PROGRAM_SIZE.

Returns:

This function returns:

• FNET_OK if successful.
• FNET_ERR if failed.

See also:

fnet_cpu_flash_erase()

This function copies FNET_CFG_CPU_FLASH_PROGRAM_SIZE bytes pointed by data to the Flash memory pointed by dest.

Disables all interrupts.

Returns:

This function returns the current IRQ status defined by fnet_cpu_irq_desc_t.

See also:

fnet_cpu_irq_enable()

This function disables all interrupts.
The interrupts can be enabled again by the fnet_cpu_irq_enable() function.

Enables interrupts.

Parameters:

irq_desc

IRQ status descriptor returned by the fnet_cpu_irq_disable() function. Pass 0 value to enable all interrupts.

See also:

fnet_cpu_irq_disable()

This function enables interrupts that were disabled by the fnet_cpu_irq_disable function.
The functions can enable all interrupts by passing into it the 0 value.

CPU-specific FNET interrupt service routine.

This is CPU-specific ISR which is executed on every FNET interrupt (from Ethernet and timer module).
It extracts vector number and calls fnet_isr_handler().

Initiates software reset.

This function performs software reset and asserts the external reset (RSTO) pin.

Reads character from the serial port.

Parameters:

port_number

Serial port number.

Returns:

This function returns:

• character received by the serial port.
• FNET_ERR if no character is available.

See also:

fnet_cpu_serial_putchar(), fnet_cpu_serial_init()

This function reads character from the serial port defined by port_number.

Initializes the serial port.

Parameters:

port_number	Serial port number.
baud_rate	Baud rate to be set to the serial port.

See also:

fnet_cpu_serial_putchar(), fnet_cpu_serial_getchar()

This function executes the HW initialization of the serial port defined by the port_number.

Writes character to the serial port.

Parameters:

port_number	Serial port number.
character	Character to be written to the serial port.

See also:

fnet_cpu_serial_getchar(), fnet_cpu_serial_init()

This function writes character to the serial port defined by port_number.
