• SPEED_CFG: Speed Configuration
Speed Configuration:
• TST_J: Test J Mode
0 = no effect.
1 = set to send the J state on the UDPHS line. This enables the testing of the high output drive level on the D+ line.
• TST_K: Test K Mode
0 = no effect.
1 = set to send the K state on the UDPHS line. This enables the testing of the high output drive level on the D- line.
• TST_PKT: Test Packet Mode
0 = no effect.
1 = set to repetitively transmit the packet stored in the current bank. This enables the testing of rise and fall times, eye pat-
terns, jitter, and any other dynamic waveform specifications.
• OPMODE2: OpMode2
0 = no effect.
1 = set to force the OpMode signal (UTMI interface) to “10”, to disable the bit-stuffing and the NRZI encoding.

Description2
Normal Mode: The macro is in Full Speed mode, ready to make a High Speed identification, if the host
supports it and then to automatically switch to High Speed mode
Reserved
Force High Speed: Set this value to force the hardware to work in High Speed mode. Only for debug
or test purpose.
Force Full Speed: Set this value to force the hardware to work only in Full Speed mode. In this
configuration, the macro will not respond to a High Speed reset handshake.
