Notes:
*1: If the application writer wants to use their own tick interrupt configuration when tickless idle
functionality is not used, please define configSETUP_TICK_INTERRUPT() (in FreeRTOSConfig.h) and provide
the configuration function. Please be aware that port.c is hard coded to use CMT0 though it seems to be
configured to use any CMTn according to the definition of configTICK_VECTOR (in FreeRTOSConfig.h).
*2: If the application writer wants to use their own tick interrupt configuration when tickless idle
functionality is used, please modify port.c for the configuration. Please be aware that port.c is
hard coded to use CMT0 though it seems to be configured to use any CMTn according to the definition of
configTICK_VECTOR (in FreeRTOSConfig.h).
*3: RX100 ports are also available.
*4: RX600 ports use MVTIPL instruction but RX610 MCUs don't support this instruction.
*5: RX700v3_DPFPU ports are also available with the following definition in FreeRTOSConfig.h.
#define configUSE_TASK_DPFPU_SUPPORT 0
*6: PriorityDefinitions.h has to be provided for port_asm.s in case of other than RX700v3_DPFPU port.
It contains two definitions of interrupt priority like the following.
#define configKERNEL_INTERRUPT_PRIORITY 1
#define configMAX_SYSCALL_INTERRUPT_PRIORITY 4
