Table 98 Overcurrent Interrupts
23.2.16 UNDERVOLTAGE INTERRUPTS
The primary UV_INT interrupt comprises fourteen secondary interrupts as described in
Section 15.13). The secondary interrupt bits are defined in Table 99.
Each of the secondary interrupts can be masked. When a mask bit is set, the corresponding interrupt
event is masked and does not trigger a UV_INT interrupt. The secondary interrupt bits in R16403
(4013h) and R16404 (4014h) are valid regardless of whether the mask bit is set. The secondary
interrupts are all masked by default.
