0 Independent operation (the output level reversal operation of pins OCU0-OCU1 is independent)
Combined operation
1 (OCU1 output pin level is inverted when output compare 0 or output compare 1 is matched in the
compare operation.)
• Specifies the output level reversal operation of pin OCU1 when free-run timer count value TCDT0
matches compare registers OCCP0, OCCP1.
• When the reverse mode bit is set to "1", the operation is as follows.
OCU0 pin: output reverses when free-run timer TCDT2 matches compare register 0 (OCCP0)
OCU1 pin: output reverses when free-run timer TCDT2 matches compare register 1 (OCCP1)
• When the reverse mode bit is set to "0", the operation is as follows.
OCU0 pin: output reverses when free-run timer TCDT2 matches compare register 0(OCCP0)
OCU1 pin: output reverses when free-run timer TCDT2 matches compare register 0 (OCCP0) or
compare register 1 (OCCP1)
Note: Reversal mode does not allow interrupts, even with cooperative operation (CMOD="1").
• For output from pins OCU0, OCU1, registers PFR15.0, PFR15.1 must be set.
• bit11-bit10: Undefined Writing does not affect the operation. The read value is "1".

To perform output on pin OCU1, general-purpose port settings must be performed.
• bit8: Pin-level settings (output compare 0)
OTD0
0 Set the output level of pin OCU0 to "L"
1 Set the output level of pin OCU0 to "H"
• To perform output on pin OCU0, general-purpose port settings must be performed.
