BIT NAME
2 OE2
1 CO2
0 CMF2
FUNCTION
Output enable:
1: The comparator output is connected to the CMP2 pin if the comparator is
enabled (CE2 = 1). This output is asynchronous to the CPU clock.
Comparator output:
Synchronized to the CPU clock to allow reading by software. Cleared when the
comparator is disabled (CE2 = 0).
Comparator interrupt flag:
This bit is set by hardware whenever the comparator output CO2 changes state.
This bit will cause a hardware interrupt if enabled and of sufficient priority.
Cleared by software and when the comparator is disabled (CE2 = 0).
