AS39513 − Detailed Description

ELOLIM[7:0] – Fourth threshold to use for limit checks during

external sensor measurements. See the section on Limit Check

Algorithm above.

EXHICNT[7:0] – Counter for the number of times that the first

threshold condition was met during limit checks of the external

sensor measurement. If this count is non-zero, the over limit

count flag, OVLIM, will be set.

EXLOCNT[7:0] – Counter for the number of times that the

second threshold condition was met (but not the first

condition) during limit checks of the external sensor

measurement. If this count is non-zero, the over limit count flag,

OVLIM, will be set.

EHICNT[7:0] – Counter for the number of times that the third

threshold condition was met (but not the first or second

condition) during limit checks of the external sensor

measurement.

ELOCNT[7:0] – Counter for the number of times that the fourth

threshold condition was met (but not the first, second, or third

condition) during limit checks of the external sensor

measurement.

EHIMAX[7:0] – Maximum count for the number of times that

the third threshold condition was met (but not the first or

second condition) during limit checks of the external sensor

measurement. If EHICNT > EHIMAX, then the over limit count

flag, OVLIM, will be set.

ELOMAX[7:0] – Maximum count for the number of times that

the fourth threshold condition was met (but not the first,

second, or third condition) during limit checks of the external

sensor measurement. If ELOCNT > ELOMAX, then the over limit

count flag, OVLIM, will be set.

Logging Control Parameters

The logging control parameter EEPROM page from addresses

0x430 through 0x43F contains parameters used during logging

and other system controls. All have the standard System level

access through RFID and SPI. This page is copied to registers at

0x630 through 0x63F during device initialization. After

initialization, if an EEPROM write occurs to these addresses

either from the RFID or SPI interface, the corresponding register

in the 0x630 through 0x63F page is also updated. In addition,

the status byte 0x43D is updated at the end of a logging event.
