Register modified Register T (implicitly)
Description This instruction alternately performs angle- and time-based operations to
generate pulse sequences, using the angle referenced time base. These
pulse sequences last for a relative duration using a free running time base.
Generally, register B holds the angle values and register A holds the time
values. Bit 0 of the conditional address field (C13) specifies whether the
instruction is operating in angle or time operation mode.
