58 / 129 page  56 Am75PDL191CHHa/Am75PDL193CHHa January 14, 2004 ADV ANCE I N FO RMAT I O N Command Definitions Tables Legend: BA = Address of bank switching to autoselect mode, bypass mode, or erase operation. Determined by A22:A20, (A21:A20 for PDL129) see Tables 4 and 5 for more detail. PA = Program Address (A22:A0) (A21:A0 for PDL129). Addresses latch on falling edge of WE# or CE#f1/CE#f2 (PDL129 only) pulse, whichever happens later. PD = Program Data (DQ15:DQ0) written to location PA. Data latches on rising edge of WE# or CE#f1/CE#f2 (PDL129 only) pulse, whichever happens first. RA = Read Address (A22:A0) (A21:A0 for PDL129). RD = Read Data (DQ15:DQ0) from location RA. SA = Sector Address (A22:A12) (A21:A12 for PDL129) for verifying (in autoselect mode) or erasing. WD = Write Data. See “Configuration Register” definition for specific write data. Data latched on rising edge of WE#. X = Don’t care Notes: 1. See Table 1 for description of bus operations. 2. All values are in hexadecimal. 3. Shaded cells in table denote read cycles. All other cycles are write operations. 4. During unlock and command cycles, when lower address bits are 555 or 2AAh as shown in table, address bits higher than A11 (except where BA is required) and data bits higher than DQ7 are don’t cares. 5. No unlock or command cycles required when bank is reading array data. 6. The Reset command is required to return to reading array (or to erase-suspend-read mode if previously in Erase Suspend) when bank is in autoselect mode, or if DQ5 goes high (while bank is providing status information). 7. Fourth cycle of autoselect command sequence is a read cycle. System must provide bank address to obtain manufacturer ID or device ID information. See Autoselect Command Sequence section for more information. 8. The data is C0h for factory or customer locked and 80h for factory locked. 9. The data is 00h for an unprotected sector group and 01h for a protected sector group. 10. Device ID must be read across cycles 4, 5, and 6. 20 for Am29PDL127H and 21 for Am29PDL129H. 11. System may read and program in non-erasing sectors, or enter autoselect mode, when in Program/Erase Suspend mode. Program/Erase Suspend command is valid only during a sector erase operation, and requires bank address. 12. Program/Erase Resume command is valid only during Erase Suspend mode, and requires bank address. 13. Command is valid when device is ready to read array data or when device is in autoselect mode. 14. WP#/ACC must be at V ID during the entire operation of command. 15. Unlock Bypass Entry command is required prior to any Unlock Bypass operation. Unlock Bypass Reset command is required to return to the reading array. Table 16.
