7.2 Connection diagrams
For the I
2
C connection, it is recommended to use 100 nF for C
1
and C
2
. Moreover, the value for the pull-up resistors R
1
and
R
2
should be based on the interface timing and the bus load; a normal value is 4.7 kΩ. Finally, a direct connection between
CSB and V
DDIO
is required. Similarly for the 4- and 3-wire SPI connections, it is suggested to use 100 nF for C
1
and C
2
.
