Specifying 64-bit addresses
The following applies to display input fields and command parameters where 64-bit addresses are supported.
A 64-bit enabled address field or command parameter can be specified by up to 16 hexadecimal digits, and might optionally include an underscore between bits 31 and 32. If an underscore is specified, then the value on the right hand side of the underscore is automatically padded with leading zeroes to form 8 digits. For example, the following are all considered identical address specifications:
100100000
1_100000
1_00100000
0000000100100000
00000001_00100000
