Note:
The DIDR provides information on the device manufacturer, the CellularRAM genera-
tion, and the specific device configuration. Table 9 describes the bit fields in the DIDR.
The DIDR is accessed with CRE HIGH and A[19:18] = 01b or through the register access
software sequence with DQ = 0002h on the third cycle.
Vendors with 256-word row lengths for CellularRAM 1.5 devices will set DIDR[15] to 1b.
