Reset value: 0000 0000 (00h)
Bits 7:6 = C0E[0:1]: COMP0 Action Bits.
These bits are set and cleared by software. They
configure the type of action to be performed on the
TxOUTB output pin when successful compare of
the CMP0R register occurs. Refer to
the list of actions that can be configured.
Bits 5:4 = C0E[0:1]: COMP1 Action Bits.
These bits are set and cleared by software. They
configure the type of action to be performed on the
TxOUTB output pin when a successful compare of
the CMP1R register occurs. Refer to
the list of actions that can be configured.
Bits 3:2 = OUE[0:1]: OVF/UNF Action Bits.
These bits are set and cleared by software.They
configure the type of action to be performed on the
TxOUTB output pin when an Overflow or Under-
flow on the U/D counter occurs. Refer to
for the list of actions that can be configured.

Bit 1 = OEV: On-Chip event on OVF/UNF.
This bit is set and cleared by software.
0: No action
1: An underflow/overflow activates the on-chip
Bit 0 = OP: TxOUTB preset value.
This bit is set and cleared by software and by hard-
ware. The value of this bit is the preset value of the
TxOUTB pin. Reading this bit returns the current
state of the TxOUTB pin (useful when it is selected
in toggle mode).
