CY:
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.

OV:
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: 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.

SMOD_1:This bit doubles the Serial Port 1 baud rate in mode 1, 2, and 3 when set to 1.
POR:
Power-on reset flag. Hardware will set this flag on a power up condition. This flag can be read
or written by software. A write by software is the only way to clear this bit once it is set.
WDIF: Watchdog Timer Interrupt Flag. If the watchdog interrupt is enabled, hardware will set this bit
to indicate that the watchdog interrupt has occurred. If the interrupt is not enabled, then this
bit indicates that the time-out period has elapsed. This bit must be cleared by software.
