Asynchronous COMMAND LATCH Cycle
A target enters low-power standby when it is disabled and is not busy. If the target is busy
when it is disabled, the target enters standby after all of the LUNs complete their opera-
tions. Standby helps reduce power consumption.
A target's bus is idle when CE# is LOW, WE# is HIGH, and RE# is HIGH.
During bus idle, all of the signals are enabled except DQS, which is not used when the
asynchronous interface is active. No commands, addresses, and data are latched into the
target; no data is output.
An asynchronous command is written from I/O[7:0], DQ[7:0] to the command register
on the rising edge of WE# when CE# is LOW, ALE is LOW, CLE is HIGH, andRE# is HIGH.
Commands are typically ignored by LUNs that are busy; however, some commands,
including READ STATUS (70h) and SELECT LUN WITH STATUS (78h), are accepted by
LUNs even when they are busy.
An asynchronous address is written from I/O[7:0], DQ[7:0] to the address register on the
rising edge of WE# when CE# is LOW, ALE is HIGH, CLE is LOW, and RE# is HIGH.
Bits that are not part of the address space must be LOW (see Table 2 on page 23). The
number of cycles required for each command varies. Refer to the command descriptions
to determine addressing requirements (see “Command Definitions” on page 39").
Addresses are typically ignored by LUNs that are busy; however, some addresses are
accepted by LUNs even when they are busy; for example, like address cycles that follow
the SELECT LUN WITH STATUS (78h) command.
