A description of the registers is below. The registers

are read only (R) or read/write (R/W). The R/W registers

are writable only if write protect has not been asserted

(see the Memory Description section).

NAME OF LOCATION

FUNCTION

00 to 01 EEPROM

R/W

TMPlimhi (MSB to LSB)

Contains upper limit settings for temperature.

If the limit is violated, a flag in Main Device

byte 70h is set.

02 to 03 EEPROM

R/W

TMPlimlo (MSB to LSB)

Contains lower limit settings for temperature. If

the limit is violated, a flag in Main Device byte

70h is set.

04 to 07 EEPROM R 00 Reserved —

08 to 09 EEPROM

R/W

limhi (MSB to LSB)

Contains upper limit settings for V

. If the

limit is violated, a flag in Main Device byte 70h

is set.

0A to 0B EEPROM

R/W

limlo (MSB to LSB)

Contains lower limit settings for V

. If the

limit is violated, a flag in Main Device byte 70h

is set.

0C to 0F EEPROM — 00 Reserved —

10 to 11 EEPROM

R/W

MON1limhi (MSB to LSB)

Contains upper limit settings for MON1. If the

limit is violated, a flag in Main Device byte 70h

is set.

12 to 13 EEPROM

R/W

MON1limlo (MSB to LSB)

Contains lower limit settings for MON1. If the

limit is violated, a flag in Main Device byte 70h

is set.

14 to 17 EEPROM — 00 Reserved —

18 to 19 EEPROM

R/W

MON2limhi (MSB to LSB)

Contains upper limit settings for MON2. If the

limit is violated, a flag in Main Device byte 70h

is set.

1A to 1B EEPROM

R/W

MON2limlo (MSB to LSB)

Contains lower limit settings for MON2. If the

limit is violated, a flag in Main Device byte 70h

is set.
