Abstract:
1. A computer system, comprising: a sensor panel; a first device configured to receive and process sense signals from the sensor panel, the first device including a first processor, a first memory and a first communication interface; and a second device, external to the first device, including a second processor, a second memory and a second communication interface, wherein the first and second devices communicate via the first and second communication interfaces implementing a predetermined communication protocol that enables an access operation to be performed on the first memory without intervention by the first processor; wherein the access operation comprises storing a boot program from the second memory to the first memory; and wherein the computer system further comprises: an attention (ATN) line connecting the first communication interface and the second communication interface; and a power manager module configured to initiate the access operation by generating a power manager boot request signal and transmitting the power manager boot request signal to the first communication interface, wherein the power manager boot request signal causes a signal on the ATN line to be set to a predetermined state.
