TBSTART The beginning of the TB count
0 Stop counting, and initialize the PWM output signal (TBIO0 pin) (PWM mode).
1 Start counting.

There is a digital filter function.
When the digital filter function is available, up to 5 sampling clock cycles of the digital filter are required for
edge detection.

There is a digital filter function.
When the digital filter function is available, up to 5 sampling clock cycles of the digital filter are required for
edge detection.
TBMDF
Selection of phase count mode
0 Increment the count
1 Phase count mode
When the TBMDF bit is "0", the counter counts the counting source set by the TBTCK0~TBTCK2 bit of the
TBCR register; When the TBMDF bit is "1", the counter pair is shown in "Table 8-15TB Registers Plus and
Subtract Conditions" The phase of the input signal at the TBCLKj pin (j=0, 1) is counted.
TBPWM Choice of PWM mode
0 Timer mode

Note 1 This bit cannot be
set when the
TBSTART bit is "0" (stop count).
2. For event (input capture
)
of the EVENTC input to be valid, the TBIO12 position of
the
TBIOR
register must be
"1"
,
and the TBIO11 bit must be combined TBIO10 position "00B" (rising edge).
