Table 18: Standard Interface Read Cycle Timing Parameters – DiskOnChip Millennium Plus 32/64MB
1. CE# may be asserted any time before or after OE# is asserted. If CE# is asserted after OE#, all timing relative to when OE#
was asserted will be referenced to the time CE# was asserted.
2. CE# may be negated any time before or after OE# is negated. If CE# is negated before OE#, all timing relative to when
OE# was negated will be referenced to the time CE# was negated.
3. The boot block is located at addresses 0000~07FFH and 1800H~1FFFH. Registers located at addresses 0800H~17FFH
have a faster access time than the boot block. Access to the boot block is not required after the boot process has completed.
4. Systems that do not access the boot block may implement only the read access timing for “all other registers”. This will
increase the systems performance, however it will prevent access to the boot block.
5. No load (C
