23.2.12 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 102.

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.

23.2.14 BATTERY CHARGER INTERRUPTS

The primary CHG_INT interrupt comprises six secondary interrupts as described in Section 17.7.8.

The secondary interrupt bits are defined in Table 103.

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 CHG_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.

CHG_OV_EINT

Battery Overvoltage interrupt

(Rising Edge triggered)

Note: Cleared when a ‘1’ is written.

CHG_END_EINT

Battery Charge End interrupt (End of

Charge Current threshold reached)

(Rising Edge triggered)

Note: Cleared when a ‘1’ is written.
