2.2.3 PROGRAM FLAG

The  PFLAG  register  contains  the  arithmetic  status  of  ALU  operation,  system  reset  status  and  LVD  detecting  status.
NT0,  NPD  bits  indicate  system  reset  status  including  power  on  reset,  LVD  reset,  reset  by  external  pin  active  and
watchdog reset. C, DC, Z  bits indicate the result status of ALU operation.  LVD24, LVD36 bits  indicate  LVD detecting
power voltage status.

Bit 5

LVD36:

LVD 3.6V operating flag and only support LVD code option is LVD_H.

0 = Inactive (VDD > 3.6V).

1 = Active (VDD

≦

3.6V).

Bit 4

LVD24:

LVD 2.4V operating flag and only support LVD code option is LVD_M.

0 = Inactive (VDD > 2.4V).

1 = Active (VDD

≦

2.4V).

Bit 2

C:

Carry flag

1 = Addition with carry, subtraction without borrowing,

rotation with shifting out logic “1”, comparison result

≧

0.

0 = Addition without carry, subtraction with borrowing signal,

rotation with shifting out logic “0”, comparison

result < 0.

Bit 1

DC:

Decimal carry flag

1 = Addition with carry from low nibble, subtraction without borrow from high nibble.
0 = Addition without carry from low nibble, subtraction with borrow from high nibble.

Bit 0

Z:

Zero flag

1 = The result of an arithmetic/logic/branch operation is zero.
0 = The result of an arithmetic/logic/branch operation is not zero.



Note: Refer to instruction set table for detailed information of C, DC and Z flags.
