Clearing registers
You can use commands to reset the status registers.
*CLS resets the bits of the event and NTR registers to 0 and sets all PTR register bits on. This
command also clears the output queue.
status.reset() resets bits of the event and NTR registers to 0 and sets all PTR register bits on.
Refer to status.reset()
In addition to these commands, you can reset the enable registers and the NTR to 0. To do this, send
the individual command to program the register with a 0 as its parameter value. The PTR registers
can be reset to their defaults by programming them with all bits on. The event registers are not
programmable but you can clear them by reading them.
Programming and reading registers
The only registers that you can program are the enable and transition registers. All other registers in
the status structure are read-only registers. The following explains how to determine the parameter
values for the various commands used to program enable registers. The actual commands are
summarized in
