PTXFSIZ PTXSA

r/r

Bits 31:16 PTXFD: Host periodic TxFIFO depth

This value is in terms of 32-bit words.

Minimum value is 16

Bits 15:0 PTXSA: 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.

r/r

Bits 31:16 INEPTXFD: IN endpoint TxFIFO depth

This value is in terms of 32-bit words.

Minimum value is 16

The power-on reset value of this register is specified as the largest IN endpoint FIFO

number depth.

Bits 15:0 INEPTXSA: IN endpoint FIFOx transmit RAM start address

This field contains the memory start address for IN endpoint transmit FIFOx. The address

must be aligned with a 32-bit memory location.
