LEGEND: R/W = Read/Write; - n = value after reset
Table 90. Transmit and Receive FIFO Register for Endpoint 1 (FIFO1) Field Descriptions
Bit Field Value Description
31-0 DATA 0-FFFF FFFF Writing to these addresses loads data into the Transmit FIFO for the corresponding endpoint.
Reading from these addresses unloads data from the Receive FIFO for the corresponding
endpoint.
The Transmit and Receive FIFO Register for Endpoint 2 (FIFO2) is shown in Figure 90 and described in
Table 91 .
