Bits 30:11 Reserved
Bits 10:6 TXFNUM: TxFIFO number
Bit 31 AHBIDL: AHB master idle
OTG_FS reset register (OTG_FS_GRSTCTL)
Address offset: 0x10
Reset value: 0x2000 0000
The application uses this register to reset various hardware features inside the core.
Bit 5 TXFFLSH: TxFIFO flush
Bit 4 RXFFLSH: RxFIFO flush
Indicates that the AHB master state machine is in the Idle condition.
Note: Accessible in both Device and Host modes.
This is the FIFO number that must be flushed using the TxFIFO Flush bit. This field must not be
changed until the core clears the TxFIFO Flush bit.

Note: Accessible in both Device and Host modes.
This bit selectively flushes a single or all transmit FIFOs, but cannot do so if the core is in the
midst of a transaction.
The application must write this bit only after checking that the core is neither writing to the
TxFIFO nor reading from the TxFIFO. Verify using these registers:
Note: Accessible in both Device and Host modes.
The application can flush the entire RxFIFO using this bit, but must first ensure that the core is
not in the middle of a transaction.
The application must only write to this bit after checking that the core is neither reading from the
RxFIFO nor writing to the RxFIFO.
The application must wait until the bit is cleared before performing any other operations. This bit
requires 8 clocks (slowest of PHY or AHB clock) to clear.
Note: Accessible in both Device and Host modes.
Read—NAK Effective Interrupt ensures the core is not reading from the FIFO
Write—AHBIDL bit in OTG_FS_GRSTCTL ensures the core is not writing anything to the
FIFO.
