Signal Description
CLK Serial Clock
SB3V3 3.3V Standby Voltage power line. Normally output power, but when Motherboard is turned
off then the on-board SPI Flash can be 3.3V power sourced via this pin.
CS0# CS0# Chip Select 0, active low.
ADDIN ADDIN input signal must be NC.
MOSI Master Output, Slave Input
ISOLATE# The ISOLATE# input, active low, is normally NC, but must be connected to GND when
loading SPI flash. Power Supply to the Motherboard must be turned off when loading SPI
flash. The pull up resistor is connected via diode to 5VSB.
MISO Master Input, Slave Output
SPI_IO2_#WP SPI Data I/O: A bidirectional signal used to support the new Dual
IO Fast Read, Quad IO Fast Read and Quad Output Fast Read modes. This signal is not
used in Dual Output Fast Read mode.
SPI_IO3_#HOLD SPI Data I/O: A bidirectional signal used to support the new Dual
IO Fast Read, Quad IO Fast Read and Quad Output Fast Read modes. This signal is not
used in Dual Output Fast Read mode.
