FPGA register details (sample circuit register)

The following functions are implemented to control the circuit to be implemented in the sample circuit.

• Always write register

• Always read register

• Write data

Write/read data control register

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 (remote 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 (remote register address: 1000_B300H to

0_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

(remote 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

(remote register address: 1000_BB00H to 1000_BBFFH).

(1) Write data control (transient area)

• 0: Disable

(2) Write data control (cyclic area)

• 0: Disable

(3) Read data control (transient area)

• 0: Disable

(4) Read data control (cyclic area)

• 0: Disable

■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.
