In the previous figures, "Slave Address" denotes the address of the F-RAM slave device. [Address
MSB: Address LSB] forms the 16-bit address of the memory location in the F-RAM to be accessed
for read/write operation. The first two bytes following the slave address byte during a write operation
constitute the initial memory address to be accessed. From there on, each byte accessed (read/
write) will increment this address by one and the count wraps around at the boundary (0x7FFF to
0x0000 for a 32 KB device). The value can be reset at any time by doing a write operation with the
desired memory address.

Example Firmware
The following steps describe how to create a project with the PSoC 4000 family that uses the
onboard F-RAM and shares it with another I
2
C master (BCP through PSoC 5LP USB-I
2
C bridge).
1. Open PSoC Creator 3.2 SP1 and create a new PSoC 4000 project, as shown in
Figure 6-16. Create a New PSoC 4000 Project in PSoC Creator
