The invention provides a method for serial data transmission. First, a chip select signal is enabled to a device for serial data transmission. Data stored in a first buffer of a controller is then transmitted to a second buffer of the device. A clock signal is then halted after data stored in the first buffer is completely transmitted. The first buffer is then refreshed with data newly received by the controller while the clock signal is halted. The clock signal is the restarted to operate the device after the first buffer is refreshed. Refreshed data stored in the first buffer is then transmitted to the second buffer while the clock signal is oscillating.

Method, system, and integrated chip for serial data transmission

An embodiment of a computer system comprises a south-bridge. The south-bridge comprises a controller including a buffer for communicating with electronic devices. When detecting that a Reset# signal is asserted, the buffer is set to a Hi-Impedance state to separate the controller from the electronic device. The Reset# signal indicates a full system reset.

Systems and methods for basic input output system (BIOS) management

The invention provides a method for Serial-Peripheral-Interface (SPI) data transmission. First, data stored in a first buffer of an SPI controller is transmitted to a second buffer of an SPI slave. A clock signal according to which the SPI slave operates is halted after data stored in the first buffer is completely transmitted. The first buffer is then refreshed with data newly received by the SPI controller while the clock signal is halted. The clock signal is then restarted to operate the SPI slave after the first buffer is refreshed. Refreshed data stored in the first buffer is then transmitted to the second buffer while the clock signal is oscillating. Halting of the clock signal, refreshing of the first buffer, restarting of the clock signal, and transmitting of refreshed data are repeated until the second buffer is full. The buffer size of the second buffer greatly exceeds that of the first buffer.
