Register-Based Programming 139
Program Timing and Execution
This section contains flowcharts and comments for using register
programming to close/open channels and synchronize the multiplexer with
a multimeter. The flowcharts identify the registers used and the status bits
monitored to ensure execution of the program.
Closing Channels The following flowchart shows how to close (or open) a multiplexer channel
and determine when it has finished closing (or opening).
Comments The address of the multiplexer Status Register is base + 04
h
. The
address of the channel register is the base address plus the channel
register offset.
Multiplexer Status Register bit 7 (the BUSY bit) is monitored to
determine when a channel has finished closing (or opening).
