ZygoStartBoardP2

Name
ZygoStartBoardP2– Starts ZYGO P2 board.
Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks input parameters value: (-17)
Description
This function allows initializing and starting the ZYGO P2 board.
Required settings to get the board up and running after power up:
Switch Settings
SW6-3:4 Set to ON ON for INT0 to deliver Axis 1 interrupts
SW6-5:6 Set to OFF ON for INT1 to deliver Axis 2 interrupts
SW6-7:8 Set to OFF OFF for sampling on SCLK1 falling edge
SW8-1:8 Set all to ON for a 00000000 base P2 address (recommendation)
This will correspond to required A11:4 on the P2 pins.
-Switch settings can be found on 2-9 in the manual.
Register Settings
Control Register 1
Bit 8 (P2 latch Mode) = 0, External sample input
Bit 9 (P2 D16 Select) = 0, for 32-bit data path
- The above must be done for both axes.
Bit 10 (P2 Sclk0 Disable) = 1
Bit 11 (P2 Sclk0 Output Enable) = 1
- The above must be done for axis 1 only.
Control Register 2
the desired Kv digital filter values, (bits 2:0)
- See section of ZMI manual for more information
Set the Change Position Direction Sense bit. This bit defines the interferometer
direction.
Setting this bit reverses the direction sense of the position accumulator. An axis
reset must be performed after changing the direction sense.
- All of the above must be done for both axes.
Data Age Adjust Program the appropriate data age adjust values
See detailed procedure below for more information
- This must be done for both axes.
P2 Interrupt Enable Select which errors will generate a signal on the P2_INT *
- This must be done for both axes.
Procedural Steps
Read the status register until Reference Present bit is present in the Status Register. This
indicates that the laser is locked. Check the Measure Present bit on each axis; when this
bit is active, perform an axis reset for that axis. Ensure Error Status Register is cleared.
Position information should now be continuously updated, as long as there are no Fatal
Errors.
Set the desired P2_RESET * line behavior (bits 6:3)
Set the desired Kp digital filter (bits 6:4)
