OTG_FS device IN endpoint transmit FIFO size register (OTG_FS_DIEPTXFx)
(x = 1..4, where x is the FIFO_number)
Address offset: 0x104 + (FIFO_number – 1) × 0x04
Reset value: 0x02000400
Host-mode registers
Bit values in the register descriptions are expressed in binary unless otherwise specified.
Host-mode registers affect the operation of the core in the Host mode. Host mode registers
must not be accessed in Device mode, as the results are undefined. Host Mode registers
can be categorized as follows:
OTG_FS host configuration register (OTG_FS_HCFG)
Address offset: 0x400
Reset value: 0x0000 0000
This register configures the core after power-on. Do not make changes to this register after
initializing the host.

Bit 2 FSLSS: FS- and LS-only support
w
r/r
w
The application uses this bit to control the core’s enumeration speed. Using this bit, the
application can make the core enumerate as an FS host, even if the connected device
supports HS traffic. Do not make changes to this field after initial programming.
This value is in terms of 32-bit words.
The power-on reset value of this register is specified as the largest IN endpoint FIFO number
depth.
This field contains the memory start address for IN endpoint transmit FIFOx.
