these bits.
This register is clocked by the 10-MHz internal oscillator. The contents of this
register are shifted to the shift register for the user logic in the application
configuration to read. When reconfiguration is triggered, this register is updated
with the contents of the update register.
This register is clocked by
by shifting data into the shift register and issuing an update. When reconfigura-
tion is triggered, the contents of the update register are written to the control
register.
After each reconfiguration, the remote system upgrade circuitry updates this
register to indicate the event that triggered the reconfiguration. This register is
clocked by the 10-MHz internal oscillator.
