Carry flag: Set for an arithmetic operation which results in a carry being generated from the
ALU. It is also used as the accumulator for the bit operations.
Auxiliary carry: Set when the previous operation resulted in a carry from the high order nibble.
User flag 0: General purpose flag that can be set or cleared by the user.
RCAP2L is also used as the LSB of a 16-bit reload value when timer 2 is configured in auto-
reload mode.
RCAP2H is also used as the MSB of a 16-bit reload value when timer 2 is configured in
auto-reload mode.
