RCAP2H Timer 2 Capture HSB: This register is used to capture the TH2 value when a timer 2 is
configured in capture mode. RCAP2H is also used as the HSB of a 16-bit reload value when timer 2 is
configured in auto-reload mode.

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: The General purpose flag that can be set or cleared by the user.
Register bank select bits:
Register bank select bits:
Overflow flag: Set when a carry was generated from the seventh bit but not from
the 8th bit as a result of the previous operation, or vice-versa.
User Flag 1: The General purpose flag that can be set or cleared by the user by
software.
Parity flag: Set/cleared by hardware to indicate odd/even number of 1's in the
accumulator.
