Description
See Table 7 for details on multiplication factor configuration.
Leave this bit at the default state.
See Table 6 for directions on programming this bit.
See Table 6 for directions on programming this bit.
0 = PLL is active
1 = PLL is inactive and in its lowest power state
0 = use this setting for PLL if the PLL reference frequency is >5 MHz.
1 = use this setting for PLL if the PLL reference frequency is <5 MHz.
0 = the PLL reference frequency = the REF_CLK input frequency.
1 = the PLL reference frequency = ½ the REF_CLK input frequency.
0 = use this setting for VCO frequencies below 100 MHz and/or to optimize for power rather
than performance.
1 = use this setting to optimize for performance; this setting results in slightly higher power
consumption. Note: When setting this bit, an IO_UPDATE must occur within 40 μs of the PLL
power-down bit (CFR2 [5]) going low.
0 = the PLL logic is reset and non-operational until this bit is set.
1 = the PLL logic operates normally.
This read-only bit is set when the REF_CLK PLL is locked.
