The ISP1362 OTG controller is designed to perform all the tasks speci
fi
ed in the OTG
supplement. It supports Host Negotiation Protocol (HNP) and Session Request
Protocol (SRP) for dual-role devices. The ISP1362 uses software implementation of
HNP and SRP for maximum
fl
exibility. A set of OTG registers provides the control and
status monitoring capabilities to support software HNP or SRP.
Besides the normal USB transceiver, timers and analog components required by
OTG are also integrated on-chip. The analog components include:
Built-in 3.3 V-to-5 V charge pump
Voltage comparators
Pull-up or pull-down resistors on data lines
Charge or discharge resistors for V
BUS
.
11.2 Dual-role device
When port 1 of the ISP1362 is con
fi
gured in the OTG mode, it can be used as an
OTG dual-role device. A dual-role device is a USB device that can function either as a
host or as a peripheral. As a host, the ISP1362 can support all four types of transfers
(control, bulk, isochronous and interrupt) at full-speed or low-speed. As a peripheral,
the ISP1362 can support two control endpoints and up to 14 con
fi
gurable endpoints,
which can be programmed to any of the four transfer types.
The default role of the ISP1362 is controlled by the ID pin, which in turn is controlled
by the type of plug connected to the mini-AB receptacle. If ID = LOW (mini-A plug
connected), it becomes an A-device, which is a host by default. If ID = HIGH (mini-B
plug connected), it becomes a B-device, which is a peripheral by default.
Both the A-device and the B-device work on a session base. A session is de
fi
ned as
the period of time in which devices exchange data. A session starts when V
BUS
is
driven and ends when V
BUS
is turned off. Both the A-device and the B-device may
start a session. During a session, the role of the host can be transferred back and
forth between the A-device and the B-device any number of times by using HNP.
If the A-device wants to start a session, it turns on V
BUS
by enabling the charge pump.
The B-device detects that V
BUS
has risen above the B_SESS_VLD level and
assumes the role of a peripheral asserting its pull-up resistor on the DP line. The
A-device detects the remote pull-up resistor and assumes the role of a host. Then,
the A-device can communicate with the B-device as long as it wishes. When the
A-device
fi
nishes communicating with the B-device, the A-device turns-off V
BUS
and
both the devices
fi
nally go into the idle state. See
Figure 18
and
Figure 19
.
If the B-device wants to start a session, it must initiate SRP by
‘
data line pulsing
’
and
‘
V
BUS
pulsing
’
. When the A-device detects any of these SRP events, it turns on its
V
BUS
(note that only the A-device is allowed to drive V
BUS
). The B-device assumes
the role of a peripheral, and the A-device assumes the role of a host. The A-device
detects that the B-device can support HNP by getting the OTG descriptor from the
B-device. The A-device will then enable the HNP hand-off by using SetFeature
(b_hnp_enable) and then go into the
‘
suspend
’
state. The B-device signals claiming
the host role by deasserting its pull-up resistor. The A-device acknowledges by going
into the peripheral state. The B-device then assumes the role of a host and
