Connecting I
2C EEPROMs
I
2C EEPROMs or other I2C compatible devices should be connected to the DIO pins DIO4 and DIO5, as shown in Figure 33.
Pull-up resistors of roughly 10k
to V3P3D (to ensure operation in BROWNOUT mode) should be used for both SCL and SDA
signals. The DIO_EEX register in I/O RAM must be set to 01 in order to convert the DIO pins DIO4 and DIO5 to I
2C pins SCL
and SDA
.
