  ADC0_KEYUP_PENDING

ADC0 Key up Pending Bit
When general key is pulled up, and the corresponding interrupt is enabled, the status bit is set.
0: No IRQ
1: IRQ Pending
Writing 1 to the bit will clear it and its corresponding interrupt if the interrupt is enabled.

  ADC0_ALRDY_HOLD_PENDING

ADC0 Already Hold Pending Bit
When hold key is pulled down and the general key is pulled down, and the corresponding interrupt is enabled.

0: No IRQ
1: IRQ Pending
Writing 1 to the bit will clear it and its corresponding interrupt if the interrupt is enabled.

  ADC0_HOLDKEY_PENDING

ADC0 Hold Key Pending Bit
When hold key is pulled down, and the corresponding interrupt is enabled, the status bit is set and the interrupt line is set.

0: NO IRQ
1: IRQ Pending
Writing 1 to the bit will clear it and its corresponding interrupt if the interrupt is enabled.

  ADC0_KEYDOWN_PENDING

ADC0 Key Down IRQ Pending Bit
When general key is pulled down, and the corresponding interrupt is enabled, the status bit is set and the interrupt line is set.

0: No IRQ
1: IRQ Pending
Writing 1 to the bit will clear it and its corresponding interrupt if the interrupt is enabled.

  ADC0_DATA_PENDING

ADC0 Data IRQ Pending Bit
0: No IRQ
1: IRQ Pending
Writing 1 to the bit will clear it and its corresponding interrupt if the interrupt is enabled.
