Tool chain used for build

The following tools have been used:

Compiler:  IAR ICCR32C V1.20A
Assembler: IAR AR32C   V1.20A
Librarian: IAR XLIB    V4.61B
Workbench: IAR EWIDE   V4.8A

Performance

1. Task switch time
   Near memory model: 9.1 us = 438 cycles
2. Interrupt latency, low priority interrupt
   Near memory model: 3.9 us = 186 cycles
3. Interrupt latency, high priority (zero latency) interrupt
   Near memory model: 0.6 us = 30 cycles
   

Absolute timings are based on an R32C running at 48 MHz and release build library

New features

Version 3.60b

1. Update to new embOS sources 3.60b
   All new features of embOS are listed in the generic release notes.
2. Support for Renesas E30A emulator
