A. HSTROBE refers to the following logical operation on HCS, HDS1, and HDS2: [NOT(HDS1 XOR HDS2)] OR HCS.
B. Depending on the type of write or read operation (HPID without auto-incrementing; HPIA, HPIC, or HPID with
auto-incrementing) and the state of the FIFO, transitions on HRDY
may or may not occur.
For more detailed information on the HPI peripheral, see the TMS320DM646x DMSoC Host Port Interface (HPI) User’s
Guide (literature number SPRUES1).
C. HCS
reflects typical HCS behavior when HSTROBE assertion is caused by HDS1 or HDS2. HCS timing requirements are
reflected by parameters for HSTROBE
.
D. For proper HPI operation, HAS
must be pulled up via an external resistor.
