The SYS_INIT_STKY bit is triggered when the SYS_INIT bit (register 0, bit 7) is trig-
gered high. It remains high until cleared. Writing a 0 to this register bit will cause it to
clear.
0: No SYS_INIT interrupt has occurred since it was last cleared.
1: A SYS_INIT interrupt has occurred since it was last cleared.
PLLB Loss Of Lock Status Sticky Bit.
The LOL_B_STKY bit is triggered when the LOL_B bit (register 0, bit 6) is triggered
high. It remains high until cleared. Writing a 0 to this register bit will cause it to clear.
0: No PLL B interrupt has occurred since it was last cleared.
1: A PLL B interrupt has occurred since it was last cleared.
PLLA Loss Of Lock Status Sticky Bit.
The LOL_A_STKY bit is triggered when the LOL_A bit (register 0, bit 5) is triggered
high. It remains high until cleared. Writing a 0 to this register bit will cause it to clear.
0: No PLLA interrupt has occurred since it was last cleared.
1: A PLLA interrupt has occurred since it was last cleared.
CLKIN Loss Of Signal Sticky Bit (Si5351C Only).
The LOS_STKY bit is triggered when the LOS bit (register 0, bit 4) is triggered high. It
remains high until cleared. Writing a 0 to this register bit will cause it to clear.
0: No LOS interrupt has occurred since it was last cleared.
1: A LOS interrupt has occurred since it was last cleared.
