0
Single A/D conversions are triggered by write to B+0.
STS stays high during the A/D conversion.
No interrupt occurs.
The user program monitors STS (Base+3, bit 7) and reads A/D data when STS
goes low.
0
1
A/D scans are triggered by write to B+0. All channels between LOW and HIGH
are sampled.
STS stays high during the entire scan (multiple A/D conversions).
No interrupt occurs.
The user program monitors STS (Base+3, bit 7) and reads A/D data when STS
goes low.

0
Single A/D conversions are triggered by the source selected with ADCLK
(Base+4, bit 4).
STS stays high during the A/D conversion.
A/D interrupt occurs when the FIFO reaches its programmed threshold.
The interrupt routine reads the number of samples equal to the FIFO threshold
(Base+5, bits 0-5).
