(a) and (b) differ as follows depending on the setting of bit 1 (TMC001) of the 16-bit timer mode control register 00
(TMC00).
(a) The TO00 output level is inverted when TM00 matches a compare register.
(b) The TO00 output level is inverted when TM00 matches a compare register or when the valid edge of the
TI000 pin is detected.
