Functional Overview
3.16 McBSP Control Registers and Subaddresses
The control registers for the multichannel buffered serial port (McBSP) are accessed using the subbank
addressing scheme. This allows a set or subbank of registers to be accessed through a single memory
location. The McBSP subbank address register (SPSA) is used as a pointer to select a particular register within
the subbank. The McBSP data register (SPSDx) is used to access (read or write) the selected register.
Table 3–16 shows the McBSP control registers and their corresponding subaddresses.
