FPGA register details (user circuit)

Write/read data control register
■Address
Name
Write/read data control register (usr_wrdat_ctrl)
■Description
The firmware controls this register and transfers data to the user circuit.
• When 1 is written to write data control (transient area/cyclic area) and read data control (transient area/cyclic area), it is
automatically cleared by hardware.
• When 1 is written to the write data control (transient area), the write data area (FPGA register address: 1000_B000H to
1000_B2FFH) is reflected in the user circuit.
• When 1 is written to the write data control (cyclic area), the write data area (FPGA register address: 1000_B300H to
1000_B3FFH) is reflected in the user circuit.
• When 1 is written to the read data control (transient area), the data from the user circuit is reflected in the read data area
(FPGA register address: 1000_B800H to 1000_BAFFH).
• When 1 is written to the read data control (cyclic area), the data from the user circuit is reflected in the read data area
(FPGA register address: 1000_BB00H to 1000_BBFFH).

■Precautions and restrictions
Write data (transient area) (FPGA register address: 1000_B000H to 1000_B2FFH) and write data (cyclic area) (FPGA register
address: 1000_B300H to 1000_B3FFH) can also be read from and written to unused areas.
