Table 14. Sub_INT1_Mask register bit description...continued

9.5.7 Sub level interrupt_2 (Sub_INT2, address 06h)

The sub-level interrupt register contains flags indicating the second-tier interrupt event.

For this register, it contains LDO1/LDO2, SW1/SW2 related interrupt events reflected on

the SW_INT and LDO_INT bits on the TOP_INT register as long as they are unmasked

on the Sub_INT2_Mask register.

This is WRITE AND CLEAR register.
