Description

Carry. This conditional status is set if a carry is generated

or no borrow. [0]

Carry Equations:

C= (Dm * Sm * Rm) + (Dm * Sm * Rm)

+(Dm * Sm * Rm)

Where: Dm destination register most significant bit

Sm - source register most significant bit

Rm - result most significant bit (stored in

destination register)

Positive. This conditional status is set if the result of an

operation is positive. [0]

Positive Equation: P = N * Z

Zero. This conditional status is set if the result of an

operation is negative. [0]

Zero Equation:Z = Rm * Rm-1 * Rm-2 * R0

Negative. This conditional status is set if the result of an

operation is negative. [0]

Negative Equation: N = Rm

Overflow. This conditional status is set if the result when an

overflow condition occurs. [0]

Overflow Equation:

V = (Dm * Sm * Rm) + (Dm * Sm * Rm)

Normalized. This conditional status is set as the result of a

long instruction and the result is normalized. [0]

Normalized Equation: J = (R32 XOR R31)

Interrupts Enabled. This bit reflects whether interrupts are

disabled or enabled. OTR Rd, ENBL and OTR Rd, DSBL

control this bit and function. [0]

Discrete Input 1. This bit reflects the input stimulus applied

to the input pin.

Receiver Error. This bit is the logical OR combination of the

OE, FE, and PE status bits. [0]

Overrun Error. When active, this bit indicates that at least

one data word was lost because the Data Ready (DR bit 0 of

the Status Register) signal was active twice consecutively

without an INR Rd, RCVR. [0]
