Q1:How long does it take to enter Holdover after writing HOLDOVER_FORCE = 1 ?

I set PLL1_LD_MUX = 0x04 (Holdover Status), HOLDOVER_EN=0; then clicked FORCE_HOLDOVER =1.  Measuring the time from start of CS* going high to the start of PLL1 LD pin going high was about 11.5 ns.

Q2:How long does it take to enter Nomal Operation after writing 0x000[7]=1 ? I believe this Reset bit is automatically cleared.

I set PLL1_LD_MUX = 0x00 (Logic Low); and PLL1_LD_TYPE = 0x04 (Output inverted).  I then clicked RESET = 1.  Measuring time from start of CS* going high to start of PLL1 LD  pin going low was about 11 ns.  Note, to lock the device, more programming will need to be done.
