CLKMODE0 equal to 0 denotes on-chip PLL bypassed
CLKMODE0 equal to 1 denotes on-chip PLL used, except when configuration bits (ED[31], ED[27], and
ED[23]) are 0 at device reset.
ED[31], ED[27], and ED[23] are the on-chip PLL configuration bits that are latched during device reset,
along with the other boot configuration bits ED[31:0].

§
Under some operating conditions, the maximum PLL lock time may vary as much as 150% from the specified typical value. For example, if the
typical lock time is specified as 100
μ
s, the maximum value may be as long as 250
μ
s.
