Clocks and Reset Generator
5.2.2.2
When the RESET# pin is asserted the CRG sets the internal reset signal. The CRG will negate the internal
reset signal approximately 16 EXTAL/CC_CLK clock ticks after the de-assertion of RESET#.
While the internal reset signal is asserted due to an external reset, the pins CLK_S[0:1] and IF_SEL[0:1]
are latched but the CLKOUT signal is still be generated.
