SC18IM704-EVB evaluation board

0x4F 0x0FF 0x50 // Set all outputs to ‘1’

0x4F 0x00 0x50 // Set all outputs to ‘0’

4.4.5 I

C clock configuration

0x57 0x07 0x05 0x08 0x00 0x50 // Set I2C clock to 375KHz

4.4.6 On-Board EEPROM write and read

0x53 0xA0 0x04 0x00 0x23 0x34 0x45 0x50 // write 0x23 0x34 0x45 to

// EEPROM address 0x00

0x53 0xA0 0x01 0x00 0x50 // reset memory location to 0x00

0x53 0xA1 0x03 0x50 // read 3 bytes from EEPROM

IM704 should return 0x23 0x34 0x45.

4.4.7 Blinking on-board LEDs

0x53 0xC4 0x06 0x11 0x97 0x80 0x00 0x00 0xAA 0x50 // write 6 control bytes to I2C blinker at address 0xC4
