Register Space When CA[46] is 1 a read or write transaction accesses the Register Space. Note: 1. CA45 may be either 0 or 1 for either wrapped or linear read. CA45 must be 1 as only linear single word register writes are supported. 5.1 Device Identification Registers There are two read only, non-volatile, word registers, that provide information on the device selected when CS# is low. The device information fields identify: Manufacturer Type Density – Row address bit count – Column address bit count Table 4.1 Memory Space Address Map Unit Type Count System Word Address Bits CA Bits Notes Rows within 64 Mb device 8192 (Rows) A21 - A9 34 - 22 Row 1 (row) A8 - A3 21 - 16 512 (word addresses) 1kbytes Half-Page 8 (word addresses) A2 - A0 2 - 0 16 bytes Table 5.1 Register Space Address Map Register System Address — — — 31-27 26-19 18-11 10-3 — 2-0 CA Bits 47 46 45 44-40 39-32 31-24 23-16 15-8 7-0 Identification Register 0 (read only) C0h or E0h 00h 00h 00h 00h 00h Identification Register 1 (read only) C0h or E0h 00h 00h 00h 00h 01h Configuration Register 0 Read C0h or E0h 00h 01h 00h 00h 00h Configuration Register 0 Write 60h 00h 01h 00h 00h 00h Configuration Register 1 Read C0h or E0h 00h 01h 00h 00h 01h Configuration Register 1 Write 60h 00h 01h 00h 00h 01h Table 5.2 ID Register 0 Bit Assignments Bits Function Settings (Binary) 15-14 Reserved Reserved 13 Reserved 0 - default 12-8 Row Address Bit Count 00000 - One Row address bit ... 11111 - Thirty-two row address bits |
