1.3.6. TCM interface

The processor can have up to two TCM memory instances, Instruction TCM (ITCM) and Data TCM (DTCM), each with a double word data width. Access to ITCM is through the ITCM 64-bit wide interface. Access to DTCM is through the D1TCM 32-bit wide interface and the 32-bit wide D0TCM interface. The DTCM accesses are split so that lower words always access D0TCM and upper words always access D1TCM. The size of both TCM instances is configurable, 4KB-16MB in powers of 2. See TCM interfaces for more information.
