See System Hold Time Calculation under Test Conditions for calculation of hold times given capacitive and dc loads.
Synchronous Read/Write—Bus Master
Use these specifications for interfacing to external memory
systems that require CLKIN—relative timing or for accessing a
slave ADSP-2106x (in multiprocessor memory space). These
synchronous switching characteristics are also valid during asyn-
chronous memory reads and writes (see Memory Read—Bus
Master and Memory Write—Bus Master).
When accessing a slave ADSP-2106x, these switching character-
istics must meet the slave’s timing requirements for synchronous
read/writes (see Synchronous Read/Write—Bus Slave). The
slave ADSP-2106x must also meet these (bus master) timing
requirements for data and acknowledge setup and hold times.
