How can I modify the frequency of the FX2LP I2C during firmware loading from the EEPROM?
FX2LP I2C controller supports I2C at 100 kHz and 400 kHz and operates at 100 kHz by default. To operate the I2C at 400 kHz during booting from the EEPROM, the configuration byte of the EEPROM should be set to 0x01.
EEPROM Configuration Byte:
To generate the IIC file using Keil uVision with this value on the configuration byte, add the following command in the post build settings of the project
hex2bix -i -f 0xC2 -c 0x01 -o <filename>.iic <filename>.hex
