+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

+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

+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
