Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-13

Unimplemented: Read as ‘0’

bit 12-10

EISEL<2:0>: ADC Core x Early Interrupt Time Selection bits

111 = Early interrupt is set and an interrupt is generated eight TADCORE clocks prior to when the data is ready

110 = Early interrupt is set and an interrupt is generated seven TADCORE clocks prior to when the data is ready

101 = Early interrupt is set and an interrupt is generated six TADCORE clocks prior to when the data is ready

100 = Early interrupt is set and an interrupt is generated five TADCORE clocks prior to when the data is ready

011 = Early interrupt is set and an interrupt is generated four TADCORE clocks prior to when the data is ready

010 = Early interrupt is set and an interrupt is generated three TADCORE clocks prior to when the data is ready

001 = Early interrupt is set and an interrupt is generated two TADCORE clocks prior to when the data is ready

000 = Early interrupt is set and an interrupt is generated one TADCORE clock prior to when the data is ready

bit 9-8

RES<1:0>: ADC Core x Resolution Selection bits

11 = 12-bit resolution

10 = 10-bit resolution

01 = 8-bit resolution

00 = 6-bit resolution

bit 7

Unimplemented: Read as ‘0’

bit 6-0

ADCS<6:0>: ADC Core x Input Clock Divider bits

These bits determine the number of Source Clock Periods (TCORESRC) for one Core Clock Period

(TADCORE).

1111111 = 254 Source Clock Periods

•

0000011 = 6 Source Clock Periods

0000010 = 4 Source Clock Periods

0000001 = 2 Source Clock Periods

0000000 = 2 Source Clock Periods

Note 1:

For the 6-bit ADC core resolution (RES<1:0> = 00), the EISEL<2:0> bits settings, from ‘100’ to ‘111’, are

not valid and should not be used. For the 8-bit ADC core resolution (RES<1:0> = 01), the EISEL<2:0> bits

settings, ‘110’ and ‘111’, are not valid and should not be used.
