SLDU007C March 2012 – November 2015 PGA450-Q1
The RAM tab is set up only for individual register read/writes without the use of the grid. When this tab is displayed, the READ SELECTED / READ ALL and WRITE SELECTED / WRITE ALL buttons perform the same operations, respectively.
The PGA450-Q1 device has 512 bytes of general-purpose RAM. This general-purpose RAM is memory-mapped into two different memory spaces inside the PGA450-Q1 device: internal memory space (0x00–0xFF) and external memory space (0x0300–0x03FF).
The user must select the appropriate memory space in the Combo Box before making the Read/Write request. Note the valid address range for the two RAM sections.
