38.9 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 38-9 are calculated when TEF starts at 0x1400.
Table 38-9. Example FIFO Configuration
FIFO Objects in FIFO Payload per Object Timestamp Bytes in Object Bytes in FIFO Start Address
TEF 12 N/A Yes 12 144 0x1400
TXQ 8 32 N/A 40 320 0x1490
FIFO 1 5 64 N/A 72 360 0x15D0
FIFO 2 16 64 Yes 76 1216 0x1738
FIFO 3 N/A - - - - 0x1BF8
