3.2 Indirect Register Map

Additional Pattern Generator features are accessed through the Indirect Address register space. These registers are read/written through the indirect access address (PGIA) and data (PGID) control registers.

Note:

Indirect Registers may only be modified while the Pattern Generator is disabled.
