Timer interrupt enable (Only one of the TINTE/DINTE/AINTE interrupts may be enabled at a
time):
0 = disabled
1 = enabled
DINTE
Digital I/O interrupt enable (Only one of the TINTE/DINTE/AINTE interrupts may be enabled
at a time):
0 = disabled
1 = enabled
AINTE
A/D interrupt enable (Only one of the TINTE/DINTE/AINTE interrupts may be enabled at a
time):
0 = disabled
1 = enabled
FIFOEN FIFO enable. When the FIFOEN = 1 and AINTE = 1, A/D interrupts occur when the FIFO
reaches its programmed threshold set with FT11-0. When FIFOEN = 0 and AINTE = 1, A/D
interrupts occur according to the following conditions: a) if SCANEN = 1, the interrupt occurs
at the end of the scan, and the FIFO contains all the samples of the scan; b) if SCANEN = 0,
the interrupt occurs after each single A/D conversion.
0 = disabled
1 = enabled
SCANEN A/D Scan enable. When SCANEN = 1, the A/D circuit performs a complete scan of all
channels between the low and high channels, inclusive, with each trigger.
0 = disabled
1 = enabled
CLKSEL A/D hardware clock select (only applies when CLKEN = 1):
0 = rising edge of counter/timer 0.
1 = falling edge on external trigger from I/O connector.
CLKEN A/D hardware clock enable. When CLKEN = 1, the A/D circuit is triggered by the hardware
clock selected with CLKSEL above, and the software A/D trigger is disabled.
0 = disabled
1 = enabled
