Target Ready
TRDY indicates a slave’s ability to
complete the current data phase of the
transaction.
indicates that valid data is present on
AD(31:0). During a write, it indicates the
target is prepared to accept data.
When the TE3-CHATT is Master, TRDY is
an input. When the TE3-CHATT is Slave,
TRDY is an output. TRDY is tri-stated,
when the TE3-CHATT is not involved in
the current transaction.
TRDY is updated and sampled on the
rising edge of CLK.
Stop
STOP is used by a slave to request the
current master to stop the current bus
transaction.
When the TE3-CHATT is bus master,
STOP is an input. When the TE3-CHATT
is bus slave, STOP is an output. STOP is
tri-stated, when the TE3-CHATT is not
involved in the current transaction.
STOP is updated and sampled on the
rising edge of CLK.
Initialization Device Select
When the TE3-CHATT is slave in a
transaction, where IDSEL is active in the
address phase and C/BE(3:0) indicates
an configuration read or write, the TE3-
CHATT assumes a read or write to a
configuration register. In response, the
TE3-CHATT asserts DEVSEL during the
subsequent CLK cycle.
IDSEL is sampled on the rising edge of
CLK.
