Synchronous Read/Write—Bus Slave
Use these specifications for 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.

NOTES
1tSRWLI (min) = 9.5 + 5DT/16 when Multiprocessor Memory Space Wait State (MMSWS bit in WAIT register) is disabled; when MMSWS is enabled,
tSRWLI (min) = 4 + DT/8.
2See System Hold Time Calculation under Test Conditions for calculation of hold times given capacitive and dc loads.
3tDACKAD is true only if the address and SW inputs have setup times (before CLKIN) greater than 10.5 + DT/8 and less than 18.5 + 3DT/4. If the address and SW inputs have
setup times greater than 19 + 3DT/4, then ACK is valid 15 + 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.
