Bit Name Description (continued)

the Timer Interrupt Clear Register. This interrupt allows waveform

generation on the analog output because the same signal that sets

the interrupt also updates the DAC output if the corresponding

TMRWG bit in the DAC Configuration Register is set. If this bit

is cleared, interrupts from EXTUPDATE* and counter A2 output

are ignored.

0 ADCINTEN A/D Conversion Interrupt Enable Bit—This bit enables or disables

generation of an interrupt at the end of an A/D conversion using

the 12-bit ADC. A DAQ operation is a multiple A/D conversion

sequence that is timed and controlled by the Lab-NB onboard

counter/timers. Whether the operation is a single or multiple

conversion, if this bit is set, an interrupt is generated whenever the

A/D FIFO contains conversion data, that is, when the A/D FIFO is

not empty. If this bit is cleared, interrupts from the A/D FIFO are

disabled.
