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

R8A66597FP/DFP/BG
2.10 SOF Control Register
Remarks
* Writing to the TRNENSEL bit is valid only when the Host Controller function is selected. The transaction validity of Hi-Speed is
not affected, although the Host Controller function is selected. This bit is common for two ports.
* While writing "BRDYM=1", write "INTL=1" (level sense).
* While writing "INTL=0", clear interrupt status, confirm "EDGESTS=0" to stop the system clock (write "SCKE=0") and then write
"SCKE=0".

This controller specifies the time period (transaction
validity) for issuing the token within one frame for
the port during Full-/Low-Speed communication.
0: Not compatible with Low-Speed
1: Compatible with Low-Speed
Specify the timing for clearing the PIPEBRDY
interrupt status.
0: Software clears the status
1: Hardware clears the status by read operation of
the FIFO buffer or by write operation to the FIFO
buffer
Specify interrupt output sense of the INT_N pin.
0: Edge sense
1: Level sense
Interrupt edge process status is set.
0: Interrupt edge non-active
1: Interrupt edge active
Select SOF pulse output mode.
00: SOF output disabled
01: SOF output in 1ms unit
10: µSOF output in 125µs unit
