<p>Digital, serial communication over an interface between an electronic device (102) and a battery (103) attached thereto comprises transmission of bytes (300) consisting of a number of bits. Each bit is defined by one of a high level and a low level, and a leading bit (304) of each byte is of a first one of said high and low levels. The method comprises the step of transmitting the other of said high and low levels for a first period of time (403, 405) immediately prior to said leading bit (304). When the leading bit of a byte is always of the same level (i.e. either high or low) and a period of the opposite level procedes the leading bit, it is very easy and simple to ensure that the sending as well as the receiving party is ready for the communication to take place and adjusted to the actual direction of communication.</p> |
