Short Read Only is enabled by setting Bit 14 of the IDMA overlay Register to 1 (0x3FE7). Short Read Only can be enabled by the processor core writing
to the register or by an external host writing to the register. Disabled by default.

Start of Read = IS Low and IRD Low. Previous data remains until end of read.
3
End of Read = IS High or IRD High.
