Abstract
A serial management interface master device includes an input/output pin and a controller including an error code calculator. The controller is configured to output a first access frame on the input/output pin to cause data to be written to a first register of a serial management interface slave device connected to the input/output pin; cause the error code calculator to generate first error code bits based on the first access frame sent to the serial management interface slave device; and output a second access frame including the first error code bits to the serial management interface slave device on the input/output pin to cause the first error code bits to be written to a second register of the serial management interface slave device.
