3.1.2 Changed items for RX62N CPU

Changed file name:[main.c] [RX62NRSK.c]

The changed items for CPU are as follows.

These should be changed as needed to match the system under development.

⎯ Initialization of the control MCU, interrupt handlers, interrupt control, DTC control, etc.

⎯ Adjustments to the duration of the specified wait time functions (usbc_cpu_DelayXms () function,

usbc_cpu_Delay1us() function)

⎯ For the non-OS firmware, settings of functions that disable or enable USB-related interrupts in order to use the

scheduler function (usb_cstd_IntDisable() function, usb_cstd_IntEnable() function)

The interrupt disable function (usb_cstd_IntDisable() function) and interrupt enable function

(usb_cstd_IntEnable() function) disable and enable, respectively, USB interrupts on the RX62N. Make any

necessary changes to the settings to match the MCU being used.

3.1.3 Changed items for H/W setting

Changed file name:[usb_cstd_Pinconfig() is included in r_usb_cSignal.c]

The changed items for Hardware setting are as follows.

⎯ External bus operating voltage (set by r_usbc_cDefUsr.h)

⎯ FIFO access endian specification (common with CPU endian mode: set by user-defined information)

⎯ Interrupt pin operation level

⎯ DTC pin operation level

⎯ Low-power sleep operation specification (set by r_usbc_cDefUsr.h)

3.1.4 Changed items for user system

Changed file name: [r_usbc_cDefUsr.h]

The items listed below should be changed to match the system under development.

⎯ Operating environment designation

⎯ USB port specification

⎯ Create Systemcall designation (uITRON)

⎯ Target device/target system designation

⎯ Installed USB-IP type designation

⎯ Transfer speed designation

⎯ CPU byte endian designation

⎯ Width of bus designation

⎯ PID = NAK setting at transfer end enable designation (peripheral function mode)

⎯ Low Power Mode designation

⎯ Software retry count at pipe no-response (host function mode)

⎯ Control read data buffer size

⎯ Device address initial value (host function mode)

⎯ Hub down port count (host function mode)
