Abstract
A serial communication system includes an integrated circuit having a master serial interface; and a processor having a slave serial interface coupled to the master serial interface through a clock signal line and a data signal line. The slave serial interface is responsive to a read temperature command issued by the master serial interface to return a first temperature value associated with the processor.

8. A method for communicating over a point to point serial communication system having a clock signal line and a data signal line coupling a serial interface master and a serial interface slave, the method comprising:
-
sending a read temperature command to the serial interface slave from the serial interface master using the clock signal line and the data signal line; and in response to the read temperature command, the serial interface slave supplying over the data signal line a temperature value associated with a processor on an integrated circuit containing the serial interface slave. - View Dependent Claims (9, 10, 11, 12, 13)
