Abstract:
1. A television signal receiver, comprising: a first circuit board including a memory and control circuitry for controlling an operation of the receiver, the control circuitry controlling the operation of the receiver in response to operational data stored in the memory; and a second circuit board operably coupled to the first circuit board via IIC bus lines, the second circuit board including a controller, coupled to the IIC bus lines, for generating first control signals in accordance with a first signal format in a first operational state and second control signals in accordance with a second signal format in a second operational state, wherein the memory and the control circuitry are coupled to the IIC bus lines, and the controller transmits the first control signals to the memory to retrieve the operational data via the IIC bus lines without affecting the control circuitry in the first operational state, and transmits the second control signals to the control circuitry to control the control circuitry in response to the retrieved operational data via the control lines.
