Hardware considerations
Pacing analog input
Hardware pacing, external or internal clock supported.
The packet size is 128 samples. Note that digital output is not compatible with concurrent
cbAInScan()/AInScan() operation, since the channel multiplexer control shares the register with the digital
output control. Writing to this register during a scan may adversely affect the scan.
Triggering and gating
Digital hardware triggering supported.
