  1. This clock signal is implemented as 'pad loopback' inside the device - the output signal is looped back through the input buffer to serve as the internal reference signal. Series termination is recommended (as close to device pin as possible) to improve signal integrity of the clock input. Any nonmonotonicity in voltage that occurs at the pad loopback clock pin between VIH and VIL must be less than VHYS.
  2. The gpio6_16.clkout1 signal can be used as an “always-on” alternative to gpmc_clk provided that the external device can support the associated timing. See Table 7-26GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Default and Table 7-28GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Alternate for timing information.
  3. The internal pull resistors for balls K7, M7, J5, K6, J4, J6, H4, H5 are permanently disabled when sysboot15 is set to 1 as described in the section Sysboot Configuration of the Device TRM. If internal pull-up/down resistors are desired on these balls then sysboot15 should be set to 0. If gpmc boot mode is used with SYSBOOT15=1 (not recommended) then external pull-downs should be implemented to keep the address bus at logic-0 value during boot since the gpmc ms-address bits are high-z during boot.
