0.9 90 A96T336 11.6.4 External Clock (XCK) External clocking is used by the synchronous or SPI slave modes of operation. External clock input from the XCK pin is sampled by a synchronization logic to remove meta-stability. The output from the synchronization logic must then pass through an ...
Because USB uses a self-clocking data format (NRZI), the SIE also inserts bits at appropriate places in the bit stream to guarantee a certain number of transitions in the serial data. This is called 'bit stuffing,' and is handled auto- matically by the MoBL-USB FX2LP18's SIE. One ...
If EKxHZ = 0, ECLKOUTx continues clocking during HOLD mode. If EKxHZ = 1, ECLKOUTx goes to high impedance during HOLD mode. F - Pin is high impedance in OFF mode (TRST = 0, EMU0 = 1, and EMU1/OFF = 0). G - Pin can be configured as a general-purpose input. H - Pin...
• Added a top-level system diagram • Added content about the ETR's interface with the TBU • Added a new Memory Requirements section • Added content about clocking architecture • Removed SPI support in tables in the Features section. Initial release SD/MMC Controller on page 280 ...

17. Although this motherboard offers stepless control, it is not recommended to perform over-clocking. Frequencies other than the recommended CPU bus frequencies may cause the instability of the system or damage the CPU. 18. While CPU overheat is detected, the system will automatically shutdown....
The ASUS EPU (Energy Processing Unit) sets the CPU in its minimum power consumption settings. Enabling this item will apply lower CPU Core/Cache Voltage and help save energy consumption. Set this item to disabled if you are over clocking the system. ...
The power- management state machine is also responsible for gating internal clocks based on the power state. Table 3-6 identifies the relationship between the D-states and bridge clock operation. Table 3-6. Clocking In Low Power States CLOCK SOURCE PCIe reference clock input (REFCLK) Internal ...
