23.2.9 OTP MEMORY INTERRUPTS
The primary OTP_INT interrupt comprises two secondary interrupts as described in Section 14.5. The
secondary interrupt bits are defined in Table 73.
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 OTP_INT interrupt. The secondary interrupt bits in R16402
(4012h) are valid regardless of whether the mask bit is set. The secondary interrupts are all masked
by default.

23.2.10 HIGH CURRENT INTERRUPTS
The primary HC_INT interrupt comprises two secondary interrupts as described in Section 15.12. The
secondary interrupt bits are defined in Table 74.
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 HC_INT interrupt. The secondary interrupt bits in R16404
(4014h) are valid regardless of whether the mask bit is set. The secondary interrupts are all masked
by default.
