FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Figure 17. SPI Communication Format
The SBC is accessible via the SPI interface in the Normal
Request mode, Normal mode, and Stand-by mode. In all
other modes (Sleep mode, Emergency mode), the voltage
supply for the microcontroller in permanently switched OFF
and the SBC input logic for MISO, MOSI, CS and SCLK isn’t
working (except SPI wake-up function in the Sleep mode).
Writing Data
To write data in a SPI register there are two, one-byte
transmissions to be performed. The first byte contains the
address of the register (MSB first) and the read/write bits
must be set to one. The second byte contains the new data
addressed by the previous byte (MSB first) and the parity
information. The calculation of the parity field P3-P0 has to
follow the equations:
Note: During the transmission of the two bytes the CS pin
remains 0. Please see Figure 18
Figure 18. Microcontroller SPI Writing Data
The SBC sends back the old address, R/W, parity, and
data information from a previous transmission. This data
contains no useful information (e.g. status). It shouldn’t be used.
In case of a wrong address field or parity mismatch, an
interrupt will be issued and the SBC retains the old state.
Reading Data
To read data from a dedicated register two, one-byte
transmissions have to be performed. The first byte contains
the address of the register (MSB first) and the read/write flags
setting to zero. The second byte needn’t contain valid data,
nevertheless, the parity calculation has to performed to avoid
an interrupt caused by a parity mismatch.
During a read operation the SBC sends back the old
address and R/W bits and the new data addressed by the first
transmitted byte starting with P3 after the last valid read/write
bit has been received.
Note: During the transmission of the two bytes the CS pin
remains zero.
