[Processor Status Register (PS)]
The processor status register is an 8-bit register consisting of 5 flags
which indicate the status of the processor after an arithmetic opera-
tion and 3 flags which decide MCU operation. Branch operations
can be performed by testing the Carry (C) flag , Zero (Z) flag, Over-
flow (V) flag, or the Negative (N) flag. In decimal mode, the Z, V, N
flags are not valid.
Bit 0: Carry flag (C)
The C flag contains a carry or borrow generated by the arithmetic
logic unit (ALU) immediately after an arithmetic operation. It can
also be changed by a shift or rotate instruction.
Bit 1: Zero flag (Z)
The Z flag is set to “1” if the result of an immediate arithmetic
operation or a data transfer is “0”, and set to “0” if the result is
anything other than “0”.
Bit 2: Interrupt disable flag (I)
The I flag disables all interrupts except for the interrupt generated
by the BRK instruction.
Interrupts are disabled when the I flag is “1”.
Bit 3: Decimal mode flag (D)
The D flag determines whether additions and subtractions are ex-
ecuted in binary or decimal. Binary arithmetic is executed when
this flag is “0”; decimal arithmetic is executed when it is “1”.
Decimal correction is automatic in decimal mode. Only the ADC
and SBC instructions can be used for decimal arithmetic.
Bit 4: Break flag (B)
The B flag is used to indicate that the current interrupt was gener-
ated by the BRK instruction. When the BRK instruction is gener-
ated, the B flag is set to “1” automatically. When the other inter-
rupts are generated, the B flag is set to “0”, and the processor
status register is pushed onto the stack.
Bit 5: Index X mode flag (T)
When the T flag is “0”, arithmetic operations are performed be-
tween accumulator and memory. When the T flag is “1”, direct arith-
metic operations and direct data transfers are enabled between
memory locations.
Bit 6: Overflow flag (V)
The V flag is used during the addition or subtraction of one byte of
signed data. It is set if the result exceeds +127 to -128. When the
BIT instruction is executed, bit 6 of the memory location operated
on by the BIT instruction is stored in the overflow flag.
Bit 7: Negative flag (N)
The N flag is set to “1” if the result of an arithmetic operation or
data transfer is negative. When the BIT instruction is executed, bit
7 of the memory location operated on by the BIT instruction is stored
in the negative flag.
