15.11 FIFO Behavior

This section explains the FIFO behavior when TEF and TXQ are enabled. FIFO 1 is configured as a TX FIFO, and FIFO 2 as an RX FIFO. The remaining FIFOs are not configured.

Note:
  1. The start addresses are calculated based on the number of objects in the FIFO and the PLSIZEx bits.
  2. The start addresses of the FIFOs given in Table 15-13 are calculated when TEF starts at 0x1400.
