Table 145 Current Sink Interrupts
The first-level EXT_INT interrupt comprises three second-level interrupts for USB, Wall and Battery
supply status. Each of these has a status bit in Register R31 and a mask bit in Register R37, as
defined in Table 146. These flags are triggered on the rising and falling edges of the interrupt events.

Table 146 External Interrupts
The first-level CODEC_INT interrupt comprises four second-level interrupts for the CODEC. Each of
these has a status bit in Register R31 and a mask bit in Register R39, as defined in Table 147. These
flags are triggered on the rising and falling edges of the interrupt events.

Flag to indicate drain voltage can no
longer be regulated and output current
may be out of spec.
(Rising Edge triggered)
Note: This bit is cleared once read.
Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
When IM_CS1_EINT is set to 1, then
CS1_EINT in R26 does not trigger a
CS_INT interrupt when set. The default
value is 0 (unmasked).
USB_FB changed interrupt.
(Rising and Falling Edge triggered)
Note: This bit is cleared once read.
WALL_FB changed interrupt.
(Rising and Falling Edge triggered)
Note: This bit is cleared once read.
BATT_FB changed interrupt.
(Rising and Falling Edge triggered)
Note: This bit is cleared once read.
Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R39 enables or masks the
corresponding bit in R31. The default
value for these bits is 0 (unmasked).
