7.15 I2C Clock Low Register (I2C_CLKLO - 0xFFE0 C310)
7.16 Interrupt handling
The CLK register holds a terminal count for counting 48 MHz clock cycles to create the
low period of the slower I
Table 375. I2C_CLKLO register (I2C_CLKLO - address 0xFFE0 C310) bit description
The interrupts set in the OTGIntSt register are set and cleared during HNP switching. All
OTG related interrupts, if enabled, are routed to the USB_OTG_INT bit in the USBIntSt
register.
I2C related interrupts are set in the I2C_STS register and routed, if enabled by I2C_CTL,
to the USB_I2C_INT bit.
For more details on the interrupts created by device controller, see the USB device
chapter. For interrupts created by the host controllers, see the OHCI specification.
The EN_USB_INTS bit in the USBIntSt register enables the routing of any of the USB
related interrupts to the VIC controller (see
Remark: During the HNP switching between host and device with the OTG stack active,
an action may raise several levels of interrupts. It is advised to let the OTG stack initiate
any actions based on interrupts and ignore device and host level interrupts. This means
that during HNP switching, the OTG stack provides the communication to the host and
device controllers.
