  • Page 89 Bit 14 is the MODID bit. When a "0" is returned in bit 14 then the module has been selected with a high state on the P2 MODID line. If a "1" is returned then the module has not been selected. This bit is read only. Keysight E1459A/Z2404B User and SCPI Programming Guide...

  • Page 90: Edge Interrupt Status Register

    A "0" means it has not been triggered yet. A bit set to "1" will only return to "0" by reading the DAV register associated with that port. Keysight E1459A/Z2404B User and SCPI Programming Guide...

  • Page 91: Watchdog Timer Control/Status Register

    When this bit is enabled the INTR line on the terminal module is active, and will be asserted as long as an edge event is captured in either edge detection register. The state of this bit is returned on a read of the register. Keysight E1459A/Z2404B User and SCPI Programming Guide...
  • Page 92 DAV ENAB = "1" allows the DAV0/2 line to cause an interrupt if enabled in the Status/Control Register. The DAV line is asserted when data is latched. This should only be enabled when in external trigger mode. When set to "0" the DAV0/2 line cannot cause an interrupt. Keysight E1459A/Z2404B User and SCPI Programming Guide...

    (If bit 1 of the Command Register Word is set to a one, then bit 2 must always be set to zero.) In the Keysight E1459A the Data Ready Marker is guaranteed to be cleared when the clock source is switched from internal to external.

    For Positive/Negative Edge Detect and Mask Registers, channels 0 through 15 are accessed when BS = 0 in the Status/Control Register.
