Not to be used with dc states on the status pins, which occur when the settings of Register 0x231, Bits[5:0] are in the range of 000000 to 001111. 1: enabled. 0: disabled. 2 STATUS0 pin divider enable Enables a divide-by-4 on the STATUS0 pin, allowing dynamic signals to be viewed at a lower frequency (such as the PFD input clocks). Not to be used with dc states on the status pins, which occur when the settings of Register 0x230, Bits[5:0] are in the range of 000000 to 001111. 1: enable. 0: disable. 1 Reserved Reserved. 0 Sync dividers (manual control) Set bit to put dividers in sync; clear bit to release. Functions like SYNC pin low. 1: sync. 0: normal. |
