5.8.3.15 Host Periodic Transmit FIFO Size Register (HPTXFSIZ, R/W, Address = 0xEC00_0100)
This register holds the size and the memory start address of the Periodic TxFIFO.
HPTXFSIZ Bit Description R/W Initial State
PTxFSize [31:16] Host Periodic TxFIFO Depth
This value is in terms of 32-bit words
•
Minimum value is 16
•
Maximum value is 7936
A new value must be written to this field. Programmed
values must not exceed the Maximum value.
R/W 16'h0300
PTxFStAddr [15:0] Host Periodic TxFIFO Start Address.
The power-on reset value of this register is the sum of the
Largest Rx Data FIFO Depth and Largest Non-periodic Tx
Data FIFO Depth
If you have programmed new values for the RxFIFO or
Non-Periodic TxFIFO, write their sum in this field.
Programmed values must not exceed the power-on value.

This register holds the memory start address of IN endpoint TxFIFOs to implement in Device mode. Each FIFO
holds the data for one IN endpoint FIFOs. This register is repeated for IN endpoint FIFO instantiated.

dr [15:0] IN Endpoint FIFOn Transmit RAM Start Address
This field contains the memory start address for IN
endpoint Transmit FIFOn.
The power-on reset value of this register is specified as
the Largest Rx Data FIFO Depth.
You have programmed a new value for RxFIFO depth,
you can write that value in this field. Programmed values
must not exceed the power-on value.
