• Manufacturer Part Number: R8A66597BG
• Description: ASSP (USB2.0 2 Port Host/1 Port Peripheral Controller)
• Manufacturer: RENESAS [Renesas Technology Corp]

R8A66597FP/DFP/BG
Remarks
* Enable the interrupt caused by the changes in status shown by each bit of the register, only when the Host Controller function
is selected.
* To clear the status of each bit of this register, use the software to write "0" only to the bit which is to be cleared, and "1" to the
other bits.
* The controller detects the change in status indicated by the OVRCR and BCHG bits of this register, even while the clock is
being stopped ("SCKE=0"), and notifies the interrupt if the corresponding interrupt is enabled. When the clock is enabled, use
the software to clear the status. Interrupt for the bits other than the OVRCR and BCHG bits cannot be detected while the clock
is being stopped ("SCKE=0").
