Table 100 Selecting USB Power Modes
The USB connection has its own first-level interrupt, USB_INT (see Section 24). This contains a
single second-level interrupt, USB_LIMIT_EINT, which indicates an over-current condition.
USB_LIMIT_EINT can be masked by setting the IM_USB_LIMIT_EINT bit.
USB Current monitoring is effective in USB Master and USB Slave Modes. The current limit
threshold is determined by USB_MSTR_500MA (in USB Master Mode) or USB_SLV_500MA (in USB
Slave Mode).

USB Limit Switch interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
When IM_USB_LIMIT_EINT is set to 1,
then USB_LIMIT_EINT in R26 does not
trigger an USB_INT interrupt when set.
The default value is 0 (unmasked).
Opens the USB switch
0 = USB enabled
1 = USB suspended
The register bit defaults to 0, when a
reset happens or LINE < UVLO or the
system fail on boot due to the upper
limit of the Hysteresis Comp not being
met.
Set the chip to be a USB master
0 = Slave
1 = Master
The register bit defaults to 0, when a
reset happens or the USB state
machine moves from MASTER mode to
SLAVE mode.
Set 500mA or 100mA mode when the
USB switch is in master mode
0 = 100mA
1 = 500mA
Set 500mA or 100mA mode when the
USB switch is in slave mode
0 = 100mA
1 = 500mA
The register bit defaults to 0, when a
reset happens or LINE<UVLO or the
system fail on boot due to the upper
limit of the Hysteresis Comp not been
met.
