Description

Note

02HEX

ZMDI_Config_2

Bits in the ZMDI_Config_2 EEPROM word control the

following settings. Important: IC must be power-cycled

after changes to this word.

0 BIN

SPI_Polarity

Configure clock polarity of SPI interface

0 = MISO changes on SCLK negative edge.

1 = MISO changes on SCLK positive edge.

2:1

00 BIN

Diag_cfg

2-bit diagnostic configuration field.

Diag_cfg[0] enables sensor connection check.

Diag_cfg[1] enables sensor short checking.

9:3

010 1000BIN

Slave_Addr

2C™ slave address (default = 28

HEX). Valid range is

00HEX to 7FHEX.

12:10

000BIN

Comm_lock

Communications address lock

§§

011 => locked

All other => unlocked

When communication is locked, I

2C™ communication

will only respond to its programmed address.

Otherwise if communication is unlocked, I

2C™ will

respond to any address.

15:13

000BIN

EEP_Lock

EEPROM lock

011 = locked

All other = unlocked

When EEPROM is locked, the internal charge pump is

disabled and the EEPROM can never be programmed

again. NOTE: Next command must be Start_NOM so

that the signature is calculated and written to

EEPROM before power down.***

03HEX

15:0

0000HEX

Offset_B

Signed 16-bit offset for bridge correction. See section

2.2.2 for details on programming Offset_B for raw data

collection.

04HEX

14:0

010 0000

0000 0000 BIN

Gain_B

15-bit magnitude of bridge gain. Always positive. Unity

is 2000HEX.

0BIN

Gain8x_B

Multiple Gain_B by 8

0 = Gain_B x 1

1 = Gain_B x 8

§§ The Comm_lock was set to 011BIN during wafer test for parts manufactured before workweek (ww) 13/2009.

*** Caution: If the part is power-cycled instead, the lock will take effect, and the checksum will be permanently wrong. In this case, the part will

always output a diagnostic state.
