DPTxFStAddr [15:0]
R_W Device Periodic TxFIFO RAM Start Address
Holds the start address in the RAM for this periodic
FIFO.
The power-on reset value of this register is sum of
the Largest Rx Data FIFO Depth, Largest Non-
Periodic Tx Data FIFO Depth, and all lower
numbered Largest Device Mode Periodic Tx Data
FIFOn Depth specified.
If you have programmed new values for the
RxFIFO, Non-Periodic TxFIFO, or device Periodic
TxFIFOs you can write their sum in this field.
Programmed values must not exceed the power-on
value set.

HOST MODE REGISTERS
These 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 :
·
Host Global registers
·
Host Port Control and Status registers
·
Host Channel-Specific registers
HOST GLOBAL REGISTERS
HOST CONFIGURATION REGISTER (HCFG)
This register configures the core after power-on. Do not make changes to this register after initializing the host.
