Pin Diagram and Pin Description
Connecting the uM-FPU to the I
If the CS pin is a logic high at reset (e.g. tied to +5V), the uM-FPU will be configured as an I
an I
shown below.
I
The slave address is 7 bits long, followed by an 8th bit which specifies whether the master wishes to write to the
slave (0), or read from the slave(1). The default slave address for the uM-FPU is 1100100x (binary).
The slave address can be changed using the built-in serial debug monitor and stored in nonvolatile flash memory.
