bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 8

COLPAR7

: Set or Cleared (1 or 0) so that this 8th parity bit (COLPAR7) + the sum of the Config. reg-

ister row parity bits contain an odd number of set (“1”) bits.

bit 7

COLPAR6

: Set or Cleared (1 or 0) such that this 7th parity bit (COLPAR6) + the sum of the 7th bits in

Config. registers 0 through 5 contain an odd number of set (“1”) bits.

bit 6

COLPAR5

: Set or Cleared (1 or 0) such that this 6th parity bit (COLPAR5) + the sum of the 6th bits in

Config. registers 0 through 5 contain an odd number of set (“1” ) bits.

bit 5

COLPAR4

: Set or Cleared (1 or 0) such that this 5th parity bit (COLPAR4) + the sum of the 5th bits in

Config. registers 0 through 5 contain an odd number of set (“1”) bits.

bit 4

COLPAR3

: Set or Cleared (1 or 0) such that this 4th parity bit (COLPAR3) + the sum of the 4th bits in

Config. registers 0 through 5 contain an odd number of set (“1”) bits.

bit 3

COLPAR2

: Set or Cleared (1 or 0) such that this 3rd parity bit (COLPAR2) + the sum of the 3rd bits in

Config. registers 0 through 5 contain an odd number of set (“1”) bits.

bit 2

COLPAR1

: Set or Cleared (1 or 0) such that this 2nd parity bit (COLPAR1) + the sum of the 2nd bits

in Config. registers 0 through 5 contain an odd number of set (“1”) bits.

bit 1

COLPAR0

: Set or Cleared (1 or 0) such that this 1st parity bit (COLPAR0) + the sum of the 1st bits in

Config. registers 0 through 5 contain an odd number of set (“1”) bits.

bit 0

R6PAR

: Register 6 Parity bit – Set or Cleared (1 or 0) so the 9-bit register contains odd (“1”) parity –

an odd number of set (“1”) bits

Note 1:

The parity bits are calculated from the configuration registers from 0 to 6 and programmed by the user. An

incorrect parity bit can cause unnecessary extra current draws although the device may function correctly.
