NOTE:
When EN0 = SEL0 = PDN0 = 0, CTRL0 also functions as a power-down. This is a special case for
situations when OUT0 is not used. Under these conditions all the circuitry associated with OUT0 is
powered down. OUT0 is powered down (see Table 2).
PDN1 (Default Setting = 0)
If PDN1 = 1, CTRL1 functions as a power-down (see Table 3).
If PDN1 = 0, CTRL1 functions as an output enable for OUT1 (see Table 3).
NOTES FOR OUTPUT ENABLE AND POWER-DOWN:
1) Both enables are “smart” and wait for the output to be low before going High-Z.
2) A power-down sequence first disables both outputs before powering down the device.
3) On power-up, the outputs are disabled until the clock has stabilized (~8000 cycles).
4) In power-down mode the device cannot be programmed.
5) A power-down command must persist for at least two cycles of the lowest output frequency plus
10s.
