These bits define the operation mode for the pin output value. Depending on the
defined mode, the level is reversed upon a match with different compare registers. See
Table 13.4-3 and Section "13.4.3 16-bit Output Compare Operation" for details.
These bits are used to enable the output compare output pins. The initial value for these
bits is "0".
• "0": General-purpose port.
• "1": Output compare pin output.
Note:
OTEn: Corresponds to output compare n.
OTEm: Corresponds to output compare m.
When they are specified as outputs, the corresponding bits of the Port Direction
Registers should also be set to "1".
These bits are used to change the pin output level when the compare pin output is
enabled. The initial value of the compare pin output is "0". Ensure that the compare
operation is stopped before a value is written. When read, these bits indicate the output
compare pin output value.
• Writing "0": Sets "0" for compare pin output.
• Writing "1": Sets "1" for compare pin output.
Note:
OTDn: Corresponds to output compare n.
OTDm: Corresponds to output compare m.
