Aspects of the invention provide a method and system for a communication bus for resetting one or more devices connected to the bus. The transceiver bus () may include a single serial data line (), a single serial clock line () and a single reset line (). A status of a slave device coupled to the transceiver bus () may be determined by a master device. Based on the status of the slave device, the master device may execute a forced reset or a normal reset. In a case where a device may be unresponsive, the master device may execute a forced reset. Additionally, in a case where a device is responsive but requires resetting, the master device may execute a normal reset and selectively reset a slave device requiring reset.

Method and system for a three conductor transceiver bus

A method and apparatus are disclosed to aid a transceiver chip, in a serial data communications system, in recovering from a system-side, out-bound data clocking problem. If a problem with a primary clock signal, used to clock data from a system-side of a transceiver chip through at least a part of an out-bound data path of the transceiver chip, is detected, then a more reliable secondary clock signal is substituted for the primary clock signal. Once it is determined that the primary clock signal has recovered, the primary clock signal is switched back to and certain discrete circuits of the out-bound data path of the transceiver chip are automatically reset in hardware without the need for system level intervention to avoid any problems due to clock glitches on the primary clock signal during the switching.
