Component: SPI Master (EB013) (E-blocks 1)

Author	Matrix TSL
Version	2.0
Category	E-blocks 1

SPI Master component

Low level routines for controlling or interacting with an SPI interface. SPI or Serial Peripheral Interface is a bus used for board level communications between devices. A target microcontroller will usually have at least one hardware SPI peripheral built in. If the hardware SPI pins are in use or more SPI channels are required then there is also a software mode available. Has additional functions to work with the E-blocks EB013 SPI hardware.

	Properties
	Connections
	Channel
SPI Channel selector
	MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode.
	MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode.
	CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master.
	DAC En
DAC enable pin - only used with the EB013 SPI E-block
	NVM En
NVM enable pin - only used with the EB013 SPI E-block
	Bus Settings
	Board Version
The Latest version of the E-block have a newer NVM IC which requires 3 address bytes instead of 2 address bytes. If you find that the NVM is not responding to commands then try changing the version property to match the version of the E-block. The version is written on the board as EB013-00-X where X is the version number.
	Prescale
Prescale option selector
	Clock Phase
Clock Phase (data change edge) selection
	Clock Polarity
Clock Polarity setting, inactive (idle) state
	Sample Point
Data bit read sample point
	Simulation
	Label
Label used to identify the component on the panel.
	Scope Traces
Selects if the scope traces are automatically generated or not
	Console Data
Selects if the console data is automatically generated or not
