The three data buffers used to hold data for both IN and OUT transactions. Each data buffer is 8 bytes long.
The reset values of the Endpoint Data Registers are unknown.
Unlike past enCoRe parts the USB data buffers are only accessible in the I/O space of the processor.

USB Mode Tables
Mode Column
The 'Mode' column contains the mnemonic names given to the
modes of the endpoint. The mode of the endpoint is deter-
mined by the four-bit binaries in the 'Encoding' column as
discussed below. The Status IN and Status OUT represent the
status IN or OUT stage of the control transfer.
Encoding Column
The contents of the 'Encoding' column represent the Mode
Bits [3:0] of the Endpoint Mode Registers (
Table 21-3
and
Table 21-4
). The endpoint modes determine how the SIE
responds to different tokens that the host sends to the
endpoints. For example, if the Mode Bits [3:0] of the Endpoint
0 Mode Register are set to '0001', which is NAK IN/OUT mode,
the SIE will send an ACK handshake in response to SETUP
tokens and NAK any IN or OUT tokens.
SETUP, IN, and OUT Columns
Depending on the mode specified in the 'Encoding' column,
the 'SETUP', 'IN', and 'OUT' columns contain the SIE's
responses when the endpoint receives SETUP, IN, and OUT
tokens, respectively.
A 'Check' in the Out column means that upon receiving an
OUT token the SIE checks to see whether the OUT is of zero
length and has a Data Toggle (Data1/0) of 1. If these condi-
tions are true, the SIE responds with an ACK. If any of the
above conditions is not met, the SIE will respond with either a
STALL or Ignore.
