DESCRIPTION

UV_DC1_EINT

DCDC1 Under-voltage interrupt.

(Rising Edge triggered)

Note: This bit is cleared once read.

R36 (24h)

Under Voltage

Interrupt Mask

11:0

“IM_” + name of respective bit

in R28

Interrupt mask.

0 = Do not mask interrupt.

1 = Mask interrupt.

Each bit in R36 enables or masks the

corresponding bit in R28. The default

value for these bits is 0 (unmasked).

24.3.3

CURRENT SINK (LED DRIVER) INTERRUPTS

The first-level CS_INT interrupt comprises two second-level interrupts for the Current Sink functions.

Each of these has a status bit in Register R26 and a mask bit in Register R34, as defined in Table

145.

Interrupt Status

CS1_EINT

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.

CS2_EINT

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.

R34 (22h)

Interrupt Status

2 Mask

13:12

“IM_” + name of respective

bit in R26

Interrupt mask.

0 = Do not mask interrupt.

1 = Mask interrupt.

Each bit in R34 enables or masks the

corresponding bit in R26. The default

value for these bits is 0 (unmasked).
