9.5.2.4 RxEvent encoding
OTG devices:
provide a minimum of 8 mA on V
there is no need for an overcurrent detection circuit because the internal A_VBUS_VLD
comparator is sufficient. If the OTG A-device provides more than 100 mA on V
overcurrent detector must be used and
The OTG A-device also uses SESS_VLD to detect when an OTG B-device is initiating

Transceiver Macrocell Interface (UTMI) Specification Ver. 1.05 . HostDisconnect is defined
in UTMI+ Specification Rev. 1.0 . A short definition is also given in the following
subsections.
Table 16.
RxActive:
RxActive event to the link. An RxActive event can be communicated using two methods.
The first method is for the ISP1507 to simultaneously assert DIR and NXT. The second
method is for the ISP1507 to send an RXCMD to the link with the RxActive field in
RxEvent bits set to logic 1. The link must be able to detect both methods. RxActive frames
the receive packet from the first byte to the last byte.
The link must assume that RxActive is set to logic 0 when indicated in an RXCMD or when
DIR is deasserted, whichever occurs first.
The link uses RxActive to time high-speed packets and ensure that bus turnaround times
are met. For more information on the USB packet timing, see
RxError:
deasserts NXT and sends an RXCMD with the RxError field set to logic 1. The received
packet is no longer valid and must be dropped by the link.
HostDisconnect:
HostDisconnect is valid only when the ISP1507 is configured as a host (both
DP_PULLDOWN and DM_PULLDOWN are set to logic 1), and indicates to the host
controller when a peripheral is connected or disconnected. The host controller must
enable HostDisconnect by setting the HOST_DISCON_R and HOST_DISCON_F bits in
the USB_INTR_EN_R_E and USB_INTR_EN_F_E registers, respectively. Changes in
HostDisconnect will cause the PHY to send an RXCMD to the link with the updated value.
