Question:

What is the usage of exclusive access memory (EAM) in Traveo™ S6J3XXX series MCUs?

Answer:

EAM is the memory area where simultaneous access by instructions (STRx, LDRx, STREXx, and LDREXx) from several CPU cores are excluded (the letter ‘x’ means the suffix of the bit range. “D”, “B”, and so on). This exclusion is used for multicore system.

Note:

This KBA applies to the following series of Traveo MCUs:

  • S6J3110
  • S6J3120
  • S6J3200
  • S6J3300
  • S6J3350
  • S6J3360
  • S6J3370
  • S6J3400
  • S6J3510
  • CY9D560

The prefix MB of the product has been changed to CY. For instance, MB9D560 has been changed to CY9D560.
