NOTES
1
t
(min) = 9.5 + 5DT/16 when Multiprocessor Memory Space Wait State (MMSWS bit in WAIT register) is disabled; when MMSWS is enabled, t
SRWLI
(min)
= 4 + DT/8.

See
System Hold Time Calculation
under Test Conditions for calculation of hold times given capacitive and dc loads.
3
t
is true only if the address and
SW
inputs have setup times (before CLKIN) greater than 10 + DT/8 and less than 19 + 3DT/4. If the address and
SW
inputs have
setup times greater than 19 + 3DT/4, then ACK is valid 14 + DT/4 (max) after CLKIN. A slave that sees an address with an M field match will respond with ACK
regardless of the state of MMSWS or strobes. A slave will three-state ACK every cycle with t
ACKTR
.

READ ACCESS
Figure 16. Synchronous Read/Write—Bus Slave
Synchronous Read/Write—Bus Slave
Use these specifications for ADSP-2106x bus master accesses of
a slave’s IOP registers or internal memory (in multiprocessor
memory space). The bus master must meet these (bus slave)
timing requirements.
