(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 V_IH and V_IL must be less than V_HYS.
(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 5-44 GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Default and Table 5-46
GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Alternate for timing information.
