INTF_CTRL - Interface Control register (address R = 07h to 09h, W = 07h, S = 08h, C = 09h) bit
description
11.1.4 OTG_CTRL register
This register controls various OTG functions of the ISP1507x1. The bit allocation of the
OTG_CTRL register is given in
Description
Interface protect disable: Controls circuitry built into the ISP1507x1 to protect the ULPI
interface when the link 3-states STP and DATA[7:0]. When this bit is enabled, the
ISP1507x1 will automatically detect when the link stops driving STP.
0b — Enables the interface protect circuit (default). The ISP1507x1 attaches a weak pull-up
resistor on STP. If STP is unexpectedly HIGH, the ISP1507x1 attaches weak pull-down
resistors on DATA[7:0], protecting data inputs.
1b — Disables the interface protect circuit, detaches weak pull-down resistors on
DATA[7:0], and a weak pull-up resistor on STP.
Indicator pass-through: Controls whether the complement output is qualified with the
internal A_VBUS_VLD comparator before being used in the V
details, see
0b — The complement output signal is qualified with the internal A_VBUS_VLD comparator
(default).
1b — The complement output signal is not qualified with the internal A_VBUS_VLD
comparator.
Indicator complement: Informs the ISP1507x1 to invert the FAULT input signal, generating
the complement output. For details, see
0b — The ISP1507x1 will not invert the FAULT signal (default).
1b — The ISP1507x1 will invert the FAULT signal.
reserved
Powers down the internal clock circuitry only. By default, the clock will not be powered in
6-pin serial mode or 3-pin serial mode.
Valid only in 6-pin serial mode and 3-pin serial mode. Valid only when SUSPENDM is set to
logic 1, otherwise this bit is ignored.
0b — Clock will not be powered in 3-pin or 6-pin serial mode (default).
1b — Clock will be powered in 3-pin and 6-pin serial mode.
reserved
3-pin full-speed low-speed serial mode: Changes the ULPI interface to a 3-bit serial
interface. The ISP1507x1 will automatically clear this bit when 3-pin serial mode is exited.
0b — Full-speed or low-speed packets are sent using the parallel interface (default).
1b — Full-speed or low-speed packets are sent using the 3-pin serial interface.
6-pin full-speed low-speed serial mode: Changes the ULPI interface to a 6-bit serial
interface. The ISP1507x1 will automatically clear this bit when 6-pin serial mode is exited.
0b — Full-speed or low-speed packets are sent using the parallel interface (default).
1b — Full-speed or low-speed packets are sent using the 6-pin serial interface.
