Register Map And Descriptions - National Instruments 6527 Series Programmer's Manual

Register Map and Descriptions

Table 2-1 shows the register map for the 6527 devices. The table gives the register name, the
register address offset from the device base address (Base Address Register 1), the size of the
register in bits, and the type of register (read-only, write-only, or read and write).
Registers are grouped in the table by function. A bit-by-bit description of each register follows
the table.
