output. The output pulse can be either low-active or high-active.
Programmable square waves can be output from the TBxxOUT pin by triggering the timer
flip-flop (TBxxFF) to reverse when the set value of the up-counter (UCO) matches the set
values of the timer registers (TBxxRG0H/L、TBxxRG1H/L). Note that the set values of
TBxxRG0H/L and TBxxRG1H/L must satisfy the following requirement:
is shifted into TBxxRG0H/L when the set value of the up-counter matches the set value of
TBxxRG1H/L. This facilitates handling of small duties.

Square waves with any frequency and any duty (programmable square waves) can be
In this mode, by enabling the double buffering of TBxxRG0H/L, the value of register buffer 0
