switching output. If configure as waveform output mode,
the port is the output pins (TBIO0, TBIO1) of compare

voltage level of compare matching pin is determined by

(2) Output timing for output comparison
A comparison match signal is generated when the contents of the TB registers are the same as the contents of
the TBGRA registers or the TBGRB registers (when the count value after the same TB registers is updated). After
generating a comparison match signal, output the output setting value of the TBIOR register from the output pins of the
output comparison (TBIO0, TBIO1). From the contents of the TB registers that are identical to the contents of the
TBGRA registers or TBGRB registers to the input clock that generates the TB registers, no comparison match signal
is generated.
The output timing for the output comparison is shown in Figure 8-20.
