HNP implementation and OTG state machine
The OTG state machine is the software behind all the OTG functionality. It is implemented
in the microprocessor system that is connected to the ISP1761. The ISP1761 provides
registers for all input status, the output control and timers to fully support the state
machine transitions in
Figure 15
and
Figure 16
. These registers include:
OTG Control register: Provides control to V
BUS
driving, charging or discharging, data
line pull-up or pull-down, SRP detection and so on.
OTG Status register: Provides status detection on V
BUS
and data lines including ID,
V
BUS
session valid, session end, overcurrent and bus status.
OTG Interrupt Latch register: Provides interrupts for status change in OTG Interrupt
Status register bits and the OTG Timer time-out event.
OTG Interrupt Enable Fall and OTG Interrupt Enable Rise registers: Provide interrupt
mask for OTG Interrupt Latch register bits.
OTG Timer register: Provides 0.01 ms base programmable timer for use in the OTG
state machine.
The following steps are required to enable an OTG interrupt:
1. Set the polarity and the level-triggering or edge-triggering mode of the HW Mode
Control register.
