Rd/Wr/S/C

10b: Enable LS transceiver

11b: Enable FS transceiver for LS packets

(FS preamble is automatically pre-pended)

Controls the internal 1.5-k

Ω pullup resister and 45-Ω HS

terminations. Control over bus resistors changes depending

on XcvrSelect, OpMode, DpPulldown and DmPulldown. Since

low speed peripherals never support full speed or hi-speed,

providing the 1.5 k

Ω on DM for low speed is optional.

Selects the required bit encoding style during transmit

00 : Normal operation

01: Non-driving

OpMode

Rd/Wr/S/C

10: Disable bit-stuff and NRZI encoding

11: Do not automatically add SYNC and EOP when

transmitting. Must be used only for HS packets.

Active High transceiver reset. After the Link sets this bit, the

TUSB1310A must assert the ULPI_DIR and reset the ULPI.

When the reset is completed, the PHY de-asserts the

ULPI_DIR and automatically clears this bit. After de-asserting

Rd/Wr/S/C

the ULPI_DIR, the PHY must re-assert the ULPI_DIR and

send an RX CMD update on the Link Layer Controller. The

Link Layer Controller must wait for the ULPI_DIR to de-

assert before using the ULPI bus. Does not reset the ULPI or

ULPI register set.

Active low PHY suspend. Put the TUSB1310A into Low

Power Mode. The PHY can power down all blocks except the

full speed receiver, OTG com-parators, and the ULPI pins.

SuspendM

Rd/Wr/S/C

The PHY must auto-matically set this bit to 1 when Low

Power Mode is exited.
