A.6 System Management Bus (SMBus)
The JRexplus-DC uses an onboard System Management Bus (SMBus). This bus is not available on a peri-
pheral connector and therefore cannot be used for external SMBus devices.
SMBus Address Device Comment
A0h / A1h SPD Eeprom (DDR-SDRAM) Part of the DDR RAM module
E2h / E3h GPIO Controller PHILIPS I/O controller PCA9538
Warning: There are more devices connected to the SMBus than listed in this table but access to these devices is not
permitted. Don’t access any other device addresses except those listed above.
