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-21065L (in multiprocessor memory space). These synchronous switching characteristics are also valid during asynchronous
memory reads and writes (see Memory Read—Bus Master and Memory Write—Bus Master).
When accessing a slave ADSP-21065L, these switching characteristics must meet the slave’s timing requirements for synchronous
read/writes (see Synchronous Read/Write—Bus Slave). The slave ADSP-21065L must also meet these (bus master) timing require-
ments for data and acknowledge setup and hold times.
