Manufacturer:NEC Description:This asynchronous input halts CPUCLK (0:3) and AGP (0:1) clocks at logic 0 level, when input low (in Mobile Mode, MODE=0) SDRAM clock output. Frequency is selected by the SD_SEL latched input. SD_SEL = 1 at power on causes SDRAM frequency = CPU frequency SD_SEL = 0 at power on causes SDRAM frequency = AGP frequency This asynchronous input halts PCICLK(0:5) clocks at logic 0 level, when input low (In mobile mode, MODE=0) SDRAM clock output. Frequency is selected by the SD_SEL latched input. SD_SEL = 1 at power on causes SDRAM frequency = CPU frenquency SD_SEL = 0 at power on causes SDRAM frequency = AGP frequency SDRAM clock outputs. Frequency is selected by the SD_SEL latched input. SD_SEL = 1 at power on causes SDRAM frequency = CPU frequency SD_SEL = 0 at power on causes SDRAM frequencies = AGP frequency Supply for SDRAM (0:11), CPU Core and 24, 48MHz clocks, nominal 3.3V. Data input for I2C serial input. Clock input of I2C input 24MHz output clock, for Super I/O timing. Pin 17, pin 18 function select pin, 1=Desktop Mode, 0=Mobile Mode. Latched Input. 48MHz output clock, for USB timing. Frequency select pin. Latched Input Along with other FS pins determines the CPU, SDRAM, PCI & AGP frequencies. CPU clock outputs, powered by VDDL2. Low if CPU_STOP#=Low Supply for CPU (0:3), either 2.5V or 3.3V nominal 14.318MHz reference clock. Latched input at Power On selects either CPU (SDSEL=1) or AGP (SD_SEL=0) frequencies for the SDRAM clock outputs. Supply for AGP (0:1) |
