89 / 111 page  M58WR064HT, M58WR064HB Common Flash Interface 89/111 Table 36. Protection Register information Offset Data Description Value (P+E)h = 47h 0001h Number of protection register fields in JEDEC ID space. 0000h indicates that 256 fields are available. 1 (P+F)h = 48h 0080h Protection Field 1: Protection Description Bits 0-7 Lower byte of protection register address Bits 8-15 Upper byte of protection register address Bits 16-23 2n bytes in factory pre-programmed region Bits 24-31 2n bytes in user programmable region 0080h (P+10)h = 49h 0000h (P+11)h = 4Ah 0003h 8 Bytes (P+12)h= 4Bh 0004h 16 Bytes Table 37. Burst read information Offset Data Description Value (P+13)h = 4Ch 0003h Page-mode read capability bits 0-7’n’ such that 2n HEX value represents the number of read- page bytes. See offset 28h for device word width to determine page-mode data output width. 8 Bytes (P+14)h = 4Dh 0004h Number of synchronous mode read configuration fields that follow. 4 (P+15)h = 4Eh 0001h Synchronous mode read capability configuration 1 bit 3-7Reserved bit 0-2’n’ such that 2n+1 HEX value represents the maximum number of continuous synchronous reads when the device is configured for its maximum word width. A value of 07h indicates that the device is capable of continuous linear bursts that will output data until the internal burst counter reaches the end of the device’s burstable address space. This field’s 3-bit value can be written directly to the read configuration register bit 0-2 if the device is configured for its maximum word width. See offset 28h for word width to determine the burst data output width. 4 (P+16)h = 4Fh 0002h Synchronous mode read capability configuration 2 8 (P+17)h = 50h 0003h Synchronous mode read capability configuration 3 16 (P+18)h = 51h 0007h Synchronous mode read capability configuration 4 Cont. Table 38. Bank and erase block region information(1) (2) 1. The variable P is a pointer which is defined at CFI offset 15h. 2. Bank Regions. There are two Bank Regions, see Appendix A, Table 29 and Table 30. Top Devices Bottom Devices Description Offset Data Offset Data (P+19)h = 52h 02h (P+19)h = 52h 02h Number of Bank Regions within the device |
