Confidential
Remarks for SPI:
The implemented SPI interface is according to a standard SPI interface.
The CL RC632 can only be addressed as a slave.
Read data:
To read out data using the SPI interface the following structure has to be used. It is possible to read out up to
n-data bytes.
The first sent byte defines both, the mode itself and the address.
byte 0
byte 1
byte 2
……..
byte n
byte n+1

data 0
data 1
……
data n-1
data n
The address byte has to fulfil the following format. The MSB bit of the first byte sets the used mode. To read
data from the CL RC632 the MSB bit is set to 1. The bits 6-1 define the address and the last bit should be
set to 0.
According to scheme above, the last sent byte has been set to 0.

Write data:
To write data to the CL RC632 using the SPI interface the following structure has to be used. It is possible to
write out up to n-data bytes.
The first send byte defines both, the mode itself and the address.

The address byte has to fulfil the following format. The MSB bit of the first byte sets the used mode. To write
data to the CL RC632 the MSB bit is set to 0. The bits 6-1 define the address and the last bit should be set to
0.
