Reads/writes a configuration register of the attached AIO-3681 module. This VI should be placed within an SCTL at or below 250 MHz. Accessing this setting requires multiple executions of the VI. Use hand shaking for valid execution. Only use one AIO Config VI per FPGA.

abc register specifies the address of the register to read/write to.
FPGA_ID register value in specifies the value to write to the given register.
FPGA_ID input valid allows you to specify TRUE to start a new register read/write transaction. A new read/write only occurs if this parameter is set to TRUE when ready for input was TRUE the previous cycle.
FPGA_ID write (T) Specifies whether the register value is modified. If TRUE, register value in will be written to the specified register on the AIO-3681 module. If FALSE, the existing register value will be read.
FPGA_ID register value out indicates the actual register value of the AIO-3681 module.
FPGA_ID output valid indicates whether the last requested register access has completed and the value of register value out is valid.
FPGA_ID ready for input indicates when the VI is in an idle state and ready to perform a new register read/write.
