Property reference

	Properties
	Device Settings
	Device Address
I2C device address bits (A2, A1, A0). Default is 0x50 (0b1010000). For 1M devices, use two component instances with addresses ending in 0 and 1.
	Device Type
Select the FRAM device type
	Memory Size (bytes)
Calculated memory size based on device type
	Address Bits
Number of address bits for selected device
	Connections
	Channel
Channel selection
	SDA
Pin used for SDA (data signal)
	SDA Remap Pin
	SCL
Pin used for SCL (clock signal)
	SCL Remap Pin
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event.
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	Simulation
	Scope Traces
Selects if the scope traces are automatically generated or not
	Console Data
Selects if the console data is automatically generated or not
	API
Specifies the API component on the panel to interact with to provide comms simulation.
