DescriptionRegister
Accessible by the logic array and clocked by RU_CLK.
•
Bits[4..0]—Contents of the status register are shifted into these bits.
•
Bits[37..0]—Contents of the update and control registers are shifted
into these bits.
Shift
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.
Control
This register is clocked by RU_CLK. The factory configuration updates this
register by shifting data into the shift register and issuing an update. When
reconfiguration is triggered, the contents of the update register are written to
the control register.
Update
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.
