• USB 2.0 host/function module
• Video display controller 5
• JPEG codec unit (RZ/A1LU only)
• OS timer
• Bus state controller
• Watchdog timer
• Multi-function timer pulse unit 2
• 12-bit A/D converter
• Serial sound interface
• Renesas SPDIF interface
• I 2
C bus interface
• Serial communication interface with FIFO
• CAN interface
• Renesas serial peripheral interface
• IEBus TM
controller (RZ/A1L only)
• CD-ROM decoder (RZ/A1L only)
• MMC host interface
• SD host interface
• Realtime clock
• SCUX
• Media local bus (RZ/A1L only)
• LIN interface (RZ/A1L only)
• Serial communication interface
• EthernetAVB (RZ/A1LU only)

When returning from the interrupt exception service routine for an interrupt request at the peripheral-module level,
execute the return instruction after clearing the source flag at the source of the request and reading the source flag so that
the interrupt request is not accidentally received again.
