ATD Digital Input Enable on channel x (x= 7, 6, 5, 4, 3, 2, 1, 0) — This bit controls the digital input buffer from
the analog input pin (ANx) to the digital data register.
0 Disable digital input buffer to ANx pin
1 Enable digital input buffer on ANx pin.
Note: Setting this bit will enable the corresponding digital input buffer continuously. If this bit is set while

ATD Compare Higher Than Register (ATDCMPHT)
Compare Operation Higher Than Enable for conversion number n (n= 7, 6, 5, 4, 3, 2, 1, 0) of a Sequence
(n conversion number, NOT channel number!) — This bit selects the operator for comparison of conversion
results.
0 If result of conversion n is lower or same than compare value in ATDDRn, this is flagged in ATDSTAT2
1 If result of conversion n is higher than compare value in ATDDRn, this is flagged in ATDSTAT2

simultaneously using it as an analog port, there is potentially increased power consumption because the
digital input buffer maybe in the linear region.
