Note for Table 6: During even (low) byte accesses, CEL# = 0, CEH# = 1. Address is applied to Memory Device 0 (S0). On 4 Mbyte
cards, address for Memory Device 2 (S2) = (Addr) + 200000h.

Note for Table 7: During odd (high) byte accesses, CEL#= 1, CEH# = 0, and address is applied to Memory Device 1 (S1). On 4 Mbyte
cards, address for Memory Device 3 (S3) = (Addr) + 200000h + 100000h.
Legend for Tables 6 and 7:
X = Don’t care
RA = Address of the memory location to be read.
RW = Data read from location RA during read operation.
PA = Address of the memory location to be programmed.
Addresses are latched on the falling edge of the WE# pulse.
PW = Data to be programmed at location PA. Data is latched on
the rising edge of WE#.
SA = Address of the sector to be erased. Refer to Table 8 for
sector addresses.
Notes for Tables 6 and 7:
1. Write protect must not be enabled for proper operation of all
commands. No command required for reading array data,
and can thus be done with write protect enabled.
2. For host-to-card address bit connections, see Figure 2.
3. All values are in hexadecimal.
4. The last bus cycle in an autoselect command sequence is a
read operation.
5. Address bits = X = Don’t Care for all commands except for
Read Address (RA), Program Address (PA), and Sector
Address (SA).
6. The Erase Suspend command is valid only during a sector
erase operation. Refer to “Sector Erase Suspend”.
7. The Erase Resume command is valid only during the Erase
Suspend mode.
8. See Table 4 for bus operations.
