Hi,
I would like to ask a question on VPBE.
In table 65 of SPRU952A, TMS320DM643x DMP Video Processing Back End (VPBE) User's Guide (Rev. A), the applicability of each register's configuration with respect to different output modes are listed, and as the footnote suggests:
R = Required,
O = Optional,
M = Master Mode,
SL = Slave Mode,
r = Read-Only Status
Whereas there does exist such specifications for a large number of registers, many are left without any specification at all.
My question is what does these "unspecified" blanks mean? If "unspecified" means "optional", then there is already "O" notation for this. Therefore it seems that blank "unspecified" means something other than "optional", yet there is no clear definition in the document.
Could anyone help on this?
