TMS320C6748: connected multiple TMS320C6748 HPI

David chen

Part Number: TMS320C6748

hi Team:

I want to connect multiple TMS320C6748 HPI interfaces together. Can I distinguish them by HCS PIN and access the HPI bus? For example, if the MCU wants to access C6748-1 HPI interfaces, it can becontrol by HCS PIN?

if not ,how to access the HPI bus that I want?

Hi David,

You are correct - you can select each HPI by asserting its chip select low. UHPI_HCS must be low for the HPI to be selected by the host.

Refer to the 20.2.3 Signal Descriptions in the TRM and 6.25.3 HPI Electrical Data/Timing in the Data Manual.
