Synchronous Read/Write—Bus Master
Use these specifications for interfacing to external memory sys-
tems that require CLKIN—relative timing or for accessing a
slave ADSP-2106x (in multiprocessor memory space). These
synchronous switching characteristics are also valid during
asynchronous memory reads and writes except where noted (see
Memory Read—Bus Master on Page 25

these switching characteristics must meet the slave’s timing
requirements for synchronous read/writes (see
