Displaying a 64 bit register

[chocotov1]

I want to check out the NVM User Row register of the SAMD21 via svd. Since it's not defined in ATSAMD21G18A.svd I tried to add it myself.

The problem is, I can only see the values that are in the first word. This register is split into two words: 0x804000 and 0x804004.

From the SAMD21 datasheet:

Here is what I added to the svd file:

      <name>NVM</name>
      <description>NVM</description>
      <baseAddress>0x804000</baseAddress>
      <registers>

          <name>USER_ROW</name>
          <description>user row 0x804000</description>
          <addressOffset>0x0</addressOffset>
          <size>0x40</size>
          <fields>

            <field>

            <field>
              <name>WDT Window</name>
              <bitRange>[34:31]</bitRange>
            </field>
            <field>

            <field>

            <field>

              <bitRange>[63:48]</bitRange>
            </field>
          </fields>
        </register>
      </registers>
    </peripheral>

The second word seems to be missing:

I haven't tried the .svd file in other software.
