sdstart
refers to the maximal response time for a serial data source to start data transmission with respect to the ris-
ing edge of the demand signal at the pin PI19.
T
sdstop
refers to the maximal response time for a serial data source to stop data transmission with respect to the fall-
ing edge of the demand signal at the pin PI19.
