The following table defines each value of type:

Value

Definition

EVEN

If

…

PARity:CHECK is ON, the received parity bit

must maintain even parity. The transmitted parity
bit will maintain even parity.

ODD

If

…

PARity:CHECK is ON, the received parity bit

must maintain odd parity. The transmitted parity
bit will maintain odd parity.

ZERO

If

…

PARity:CHECK is ON, the received parity bit

must be a zero. The transmitted parity bit will be a
zero.

ONE

If

…

PARity:CHECK is ON, the received parity bit

must be a logic one. The transmitted parity bit will
be a logic one.

NONE

A parity bit must not be received in the serial data
frame. No parity bit will be transmitted.

While this command operates independently of either the

…

BITS or

…

SBITs commands, there are two combinations which are disallowed

because of their data frame bit width. The following table shows the
possible combinations:

Received parity will not be checked unless

…

PAR:CHEC ON is has been

sent. Transmitted data will include the specified parity whether

…

PAR:CHEC is ON or OFF.

•

DIAG:BOOT:COLD will set

…

PARity to NONE.
