Improvements

Version 3.88e

  1. NONE, initial version for embOS Cortex M TICC.

Program corrections

Version 4.24

  1. Applied workaround for interrupt handling with Cortex-M7 r0p1.
    Erratum 837070, ARM-EPM-064408: Increasing priority using a write to BASEPRI does not take effect immediately. Appropriate workaround was applied. The problem, which is exclusive for Cortex-M7 r0p1, existed on all previous versions of embOS Cortex M SES and is fixed with version 4.24.
