Bits 27:24 – WKUPCLKCNT[3:0] Wake-up Clock Count bits

These bits represent the number of ADC clocks required to warm-up the ADC module before it can perform conversion. Although the clocks are specific to each ADC, the WKUPCLKCNT bit is common to all ADC modules.

0010	2⁴= 16 clocks
0001	2⁴= 16 clocks
0000	2⁴= 16 clocks

Bit 23 – WKIEN7 Shared ADC Wake-up Interrupt Enable bit

Value	Description
1	Enable interrupt and generate interrupt when the WKRDY7 status bit is set
0	Disable interrupt

Bit 15 – WKRDY7 Shared ADC Wake-up Status bit

Note: This bit is cleared by hardware when the ANEN7 bit is cleared.

Value	Description
1	ADC Analog and bias circuitry ready after the wake-up count number 2^WKUPEXP clocks after setting ANEN2 to ‘`1`’
0	ADC Analog and bias circuitry is not ready

Bit 7 – ANEN7 Shared ADC Analog and Bias Circuitry Enable bit

Value	Description
1	Analog and bias circuitry enabled. When the analog and bias circuit is enabled, the ADC module needs a warm-up time, as defined by the ADCANCON.WKUPCLKCNT[3:0] bits.
0	Analog and bias circuitry disabled
