24.3 SECOND-LEVEL INTERRUPTS
w
The following sections define the second-level interrupt status and control bits associated with each
of the first-level bits defined in Table 141.
24.3.1
The first-level OC_INT interrupt comprises one second-level interrupt for the limit switch. This status
bit is in Register R29 and its mask bit is in Register R37, as defined in Table 142.

24.3.2
The first-level UV_INT interrupt comprises several second-level interrupts for the DC-DCs and LDOs.
Each of these has a status bit in Register R28 and a mask bit in Register R36, as defined in Table
143.

Note: This bit is cleared once read.
Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
When IM_OC_LS_EINT is set to 1, then
OC_LS_EINT in R29 does not trigger an
OC_INT interrupt when set. The default
value is 0 (unmasked).
LDO4 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
LDO3 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
LDO2 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
LDO1 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
DCDC6 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
DCDC5 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
DCDC4 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
DCDC3 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
DCDC2 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
