Production Data

Each DC-DC Converter has a dedicated second-level interrupt which indicates an under-voltage
condition. These can be masked by setting the applicable mask bit as defined in Table 80.

Note: there is no over-current fault condition for converter 2.
Table 80 DC-DC Converter Interrupts
The /VCC_FAULT output is configurable by the control fields in Register R215. The fields described
in Table 81 determine which of the DC-DCs contribute to the /VCC_FAULT indication. An
undervoltage or overvoltage condition on any unmasked DC-DC Converter will cause the
/VCC_FAULT output to be set to logic low.

VCC_FAULT
Table 81 DC Converter /VCCFAULT Mask Bits
The DC-DC Converters and the LDO Regulators have a first-level interrupt, UV_INT (see Section 24).
This comprises second-level interrupts from each of the DC-DC Converters and the LDO Regulators.
The status of the DC-DC Converters can be indicated and monitored externally via a GPIO pin
configured as /VCC_FAULT (see Section 20). When a GPIO pin is configured as /VCC_FAULT
output, a logic low level on this pin indicates that there is a fault condition on one of the LDO
Regulators, DC-DC Converters, or the Current Limit switch.

Note: This bit is cleared once read.
DCDC3 Under-voltage interrupt.

DCDC1 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
Mask bits for DC-DC converter under-
voltage interrupts
Each of these bits masks the respective
bit in R28 when it is set to 1 (e.g.
UV_DC1_EINT in R28 does not trigger a
UV_INT interrupt when IM_UV_DC1_EINT
in R36 is set).
DCDC4 fault mask for the /VCC_FAULT
0 = don't mask converter fault
1 = mask converter fault
DCDC3 fault mask for the /VCC_FAULT
0 = don't mask converter fault
1 = mask converter fault
DCDC2 fault mask for the /VCC_FAULT
0 = don't mask converter fault
1 = mask converter fault
DCDC1 fault mask for the /VCC_FAULT
0 = don't mask converter fault
1 = mask converter fault
